2027 Tiffin Motorhomes Allegro Bay 34 DB Review
If you’re looking to up your towing game with an RV that can bring the goods and do so in style, Tiffin Motorhomes’ 2027 Allegro Bay 34 DB might be a great choice. With strong towing and a premium interior, the Allegro Bay lineup brings the Tiffin Motorhomes brand into the Super C world. These rigs incorporate the BrakeSync towing system inherited from their Freightliner chassis and offer surprising comfort and style with truck-like capability.
Further, this RV is short enough to be relatively maneuverable but still has a king-sized bed and a very nice interior. It would make a great couple’s camper.
All this is just the tip of the proverbial iceberg! Let’s take a closer look.
At a Glance: Allegro Bay 34 DB
I rated the 2027 Tiffin Motorhomes Allegro Bay 34DB an 8.4 out of 10. Much of this RV actually did really well in our scoring model — with no category earning less than an 8 and many earning a score of 9 out of 10.

- All-composite sidewall
- Strong off-grid camping ability
- Luxurious features and finishes
- Front paint-protection film
Benefits
- Towing is a primary feature. Towing is a big reason people buy Super C motorhomes, And model is able to pull 12,000 pounds. Additionally, the Freightliner BrakeSync helps make braking safer and improves the towing experience.
- Keeping the paint looking good longer. There’s a thin, clear layer of plastic over the paint on the front of the Tiffin Motorhomes Allegro Bay 34 DB that helps protect the paint from rocks and other things that might otherwise damage the finish.
- Build quality. The sidewalls are built using an all-composite process where fiberglass is laminated to a man-made substrate (Azdel) which forms a bond and is not damaged by water. There is also a gel coat on top of the fiberglass which makes for a very smooth surface. So, this wall construction is both attractive and should be very long-lasting.
- Off-grid camping champ. With large holding tanks, an on-board generator, Shower Miser water-saving feature, and more, this RV can easily spend a good amount of time at shows and events where there are no hook-ups.
- An iron fist in a velvet glove. Despite the truck-like origins of this RV it manages to come across as a luxurious and comfortable space to be despite having first-rate cargo and towing functionality of the truck chassis.
Challenges
- PEX clamps on plumbing fixtures. All the Tiffin models we saw featured a lot of plumbing fixtures with what appear to be PEX clamps on flexible hoses. A company spokesperson said that they aren’t having issues with this type of fitting. Even so, these common connections in the RV industry are very much a challenge and tend to leak. I’m not going to emphatically state that these are leak-prone. However, it is an area I would very keenly watch if I were an owner.
- Overall size. Let’s just say that fitting into trim little campsites is probably not going to be the strength of this model. While it has the power and the holding tanks to make it’s own place and stay there off-grid, it will likely need some berth in its site selection.
Best For
- Motorhome enthusiasts who need to tow in horse shows, car racing, collectible car events, or trade shows (This would be a very upscale way to attend those events.)
- Road hosts who might occasionally travel with younger travelers (like grandkids) who can hop into with the overcab bed
Key Areas We Evaluate for RV Buyers
Sleeping Space: 9/10
There are a number of choices you can make when ordering the Allegro Bay 34 DB depending on how big your crew is. Starting at the back, there’s a 72-inch-by-80-inch king-size bed. (But queen-size bed is also an option.) The Allegro Bay 34 DB comes standard with a 74-inch sofa bed in the living area, but the unit we saw had the optional dual theater seats. There’s also a bunk over the cab, and the space is tall enough that even an adult could sit up here. (It does, however, have a weight capacity of 300 pounds.)
As for the bedroom, the king-size bed does limit the size of the night stands on either side, but, for those who might utilize something like a CPAP, Tiffin Motorhomes has provided a 120-volt AC power outlet in the overhead cabinet which might enable putting the device up there.
There is good storage at the foot of the bed, which is on the road side of this RV in a very large slide. There is an option for a washer and dryer in the storage area in exchange for cabinet space. (It’s all about your priorities, as usual.)
Bathroom: 8/10
The bathroom in the Allegro Bay 34 DB can almost be described as a typical RV bathroom — and no, that’s not meant as a negative. (Just an observation.) There’s a ceramic toilet and an L-shaped counter which includes a sink. A bit of storage is provided in an overhead cabinet. Plus, there’s also a medicine cabinet.
The rectangular shower is the highlight of this space, with a segmented-glass, sliding door and a nicer showerhead. There’s also a step in here and a cubby for soaps and such. Tiffin Motorhomes has also employed the Shower Miser system to help save water when camping off the grid.
As with other Tiffin Motorhomes models, this one has a sliding panel that can block out the skylight and features a built-in light.
Living Area: 8/10
Similar to other larger Tiffin offerings, the Allegro Bay 34 DB gives a few choices for buyers in the seating area. The unit I saw had theater seats on the road side of the interior cabin, which were finished in a faux-leather material. These were power-operated and directly faced the TV. Overhead were some of the many cabinets that provide good storage inside.
On the camp side was fitted a table arrangement where the free-standing chairs could be used in a desk-like arrangement facing the outside of the RV. There is also a flip-up table on this cabinet. So, the two chairs could be used facing one another for dining or a game of cards.
The space itself is very pleasant with a padded ceiling that features a decorative fixture that incorporates the lighting.
Kitchen: 8/10
Like an increasing number of motorhomes, the Allegro Bay 34 DB has no propane aboard, which means the kitchen is all-electric. That translates into a two-burner induction cooktop and a large residential-sized microwave that offers a convection function.
There is also a residential refrigerator with ice maker, but I find this odd. After all, there are plenty of RV-specific 12-volt refrigerators that are designed for mobile environments and wouldn’t require using the inverter to operate. Curious.
There are counter sections that can cover the induction cooktop and the two-bowl sink. With these in place you get additional counter space for prep and serving. I’m curious how many owners have just removed these and left them behind. (I can imagine the rattling of these hard-surface covers becoming grating on long drives.)
As for kitchen storage, there are a variety of drawers and cabinets that provide a good amount of storage space.
Four-Season Capabilities: 8/10
The compartments with holding tanks feature heating to prevent them from freezing, as does the wet bay compartment with the hook-ups for water. One of the areas where winter can sneak in is the outdoor shower on some RVs but the one here is enclosed with the rest of the wet bay in the heated compartment. (Nicely done!)
On the flip side of the thermometer, this coach features two 15,000-Btu roof-mounted air conditioners to help tame the heat in summer.
Storage Space: 9/10
Inside the Allegro Bay 34 DB, there are a lot of cabinets and drawers — with one particularly clever cabinet that opens on a corner right at the entry door. One could also repurpose the bunks over the cab for storage for larger items. (Especially with the knowledge that the center of this is intended to flip up and provide easier access to the cab from the RV in back.)
Outside, Tiffin Motorhomes carries on its tradition of concealing basement storage behind extremely well-made doors that have a very reassuring feel to them.
The basement storage on this rig isn’t quite as commodious as on a Class A, but it’s also not bad and certainly more sizable than most towables could offer.
The compartments themselves are lined with a waterproof material that feels like the bed liner on a pickup truck. In addition to the main storage in the compartment, there is a bit of space above it where the opening reaches the other side of the motorhome. Perhaps, this could be used for skis or a table or similar item that is long but not very tall. But the frame on this truck does preclude a full passthrough storage compartment.
Chassis/Suspension: 9/10
The chassis on this truck is inherited from Freightliner as is the cab, with the rear RV portion being built by Tiffin. Front suspension is leaf springs whereas the rear suspension is an air-ride system. There is a built-in air compressor on this rig. It feeds the rear suspension but can also be used to inflate tires and such. That air system also feeds a braking system that can provide braking capability to a towed vehicle or trailer.
The focus of this rig is on capability, with a heavy-duty chassis designed for towing — up to 12,000 pounds as configured. The RV is built on a Freightliner S2RV chassis with motivation coming from a Cummins B6.7 360-horsepower diesel that produces 800 pounds-feet of torque. That should do the trick of hustling this around, including when there’s a significant trailer in tow.
Cockpit: 8/10
The cab of the Allegro Bay 34 DB is inherited from the Freightliner chassis the RV rides on, and while it might be assumed this is very truck-like it’s actually not unpleasant.
Controls are well-placed, and the seating position offers a good view of the road. There are cameras to monitor the lanes alongside you. So, getting used to driving this rig may be easier than expected. The seats are quite nice with a faux leather finish and a wide range of adjustments. They are also mounted on an air-shock system to absorb some of the harshness of the commercial chassis.
An overhead binnacle provides a place for the stuff that just seems to accumulate as we meander down the road of adventure.
Off-Grid/Sustainability: 9/10
With huge holding tanks and an included generator, Super Cs, in general, are well-suited to off-grid camping. Considering how many of these are used for towing things like horse trailers and off-road vehicles, the ability to camp off the grid is a natural evolution.
It’s odd, to me, that an RV so well-suited to off-grid camping is saddled with a residential refrigerator. There are plenty of RV-specific, 12-volt fridges that are designed for off-grid use and don’t require the use of an onboard inverter.
On that subject, the Allegro Bay 34 DB comes with a 3,000-watt, pure-sine-wave inverter. The standard batteries are AGM batteries, but, fortunately, you can get a 270-amp-hours lithium battery instead. The AGM batteries have a similar rating to the lithium battery, but you can really only use half the rated capacity of any flooded battery so the lithium offers far more power in reserve.
No solar panels are standard but 600 watts of solar is an option. There is also a provision to automatically start the built-in, 8-kilowatt diesel generator if it’s needed to recharge the battery or provide power to operate systems inside the rig.
This RV also has a huge fresh-water holding tank at 150 gallon, and Tiffin has fitted the bathroom with a device called the Shower Miser that redirects water back into the system while you’re waiting for it to get hot at the shower, which can save a significant amount of water while off-grid camping.
Value: 8/10
This is a highly subjective category, but I appreciated how the walls and cargo bay doors are built. Tiffin Motorhomes does credit to it reputation for quality and premium products with the Allegro Bay 34 DB. That same quality and attention carried through many of the components and systems in this RV. So, to me, the Allegro Bay 34 DB represents a solid value.
The big questions, in my mind, were the plumbing fittings. This type can be prone to leaking if incorrectly installed. (Tiffin Motorhomes says that is not a concern here.) I also noticed that the drawers had an almost unfinished feel to them with a brad-nailed build. Normally, this wouldn’t have been a big deal. However, even some midgrade travel trailers now are using dovetailed drawer construction, and those drawers are very well-finished. While this might seem like a minor detail, it’s something you’re going to touch every day.
Build Quality Highlights
I alluded to this earlier, but one of the highlightsare the outside baggage compartment doors. They have an aircraft-like feel to them. (Providing a reassuring thunk when closing.) These really impart a very high-quality feel. Also, the walls of these RVs are a sandwich of all synthetic materials. That means that they are not damaged by water. The exterior is a gel coat, which really offers a nice automotive finish to it. The inner layer is a man-made substrate. That, again, is also impervious to water damage.
The windows in the Allegro Bay 34 DB are of the frameless variety. Nicely, they present less maintenance concerns, since the seals are secured behind the outer glass.
Closing Notes on the Allegro Bay 34 DB
For those who want the truck-like towing capabilities in a Super C but with a more prestigious branding, Tiffin Motorhomes’s foray into the field might be the way to go. There is all the capability of the Freightliner truck chassis combined with nice interior pieces and a fully painted exterior. (Although not everyone appreciates the swooshes and swirls that are common on Tiffin-branded products. Looking at you, Brinkley RV.) Still, this is a worthy competitor in a market that’s getting more crowded with good choices.
