The Allegro Bay comes standard with Truma AquaGo Comfort Instant Water Heater and a 24-gallon liquid propane tank. You also have the option for the “All-Electric Coach” that features the AquaHot UltraCompact Hydronic Heating System and an induction cooktop which eliminates the need for the propane tank.
MAKE ROOM FOR LARGER PETS.
The Allegro Bay’s 12,000 lb tow capacity helps relieve the concern of what you can take on your next adventure.
MAKE ROOM FOR LONGER STAYS.
The Allegro Bay is dry camp ready thanks to the 150-gallon fresh water tank. To help extend your stay even longer, the Aqua View Showermiser is equipped to conserve both your fresh water and grey tank capacities.
MAKE ROOM FOR EFFICIENT POWER.
With the Allegro Bay, we kept the adventure-ready owner in mind all the way through the development process. With either the standard AGM Extended Cycle House Batteries or the optional Lithium Ion House Batteries, you'll be able to continue your adventure for a longer period of time.
The Allegro Bay Freightliner Custom Chassis comes standard with a full-time NoSPIN® differential single rear axle. Full-time traction control minimizes or eliminates wheelspin in wet and adverse conditions like mud and snow.
MANUAL RELEASE VALVE FOR REAR AIR SUSPENSION
Unhitching a trailer or boat with the Allegro Bay is a cinch with the manual release valve for the rear suspension. It gives you the option to dump “all, some, or none” of the air bags on command and will start to automatically fill when going 5 mph.
LED LIGHTS
The Freightliner Custom Chassis’s optional LED headlights provide superior nighttime visibility for improved object detection in the Allegro Bay. They also reduce eyestrain for drivers and minimizes harsh headlight glare for oncoming traffic. With little to no headlight maintenance over the life of the vehicle, you can focus more on the adventures ahead.
SLOPED DASH FOR BETTER VISIBILITY
The sloped dash on the Allegro Bay Freightliner Custom Chassis helps ensure forward visibility while also helping reduce blind spots and potential hazards by providing better visibility. A combination of an automotive-style, ergonomically designed dash, sloped hood, and a larger windshield helps further increase line of sight for the driver and helps reduce blind spots and potential hazards.
CUMMINS B6.7 360 HP DIESEL ENGINE
American ingenuity and over 30 years of continuous improvement have made the Cummins B6.7 a standard in reliability and performance for motorhomes and thousands of other applications.
AUTO DRAIN VALVE WITH HEATER ON ALL AIR TANKS
Auto drain valves relieve the need for the cargo storage compartment pull drain cords that you will find in the competition. These air tanks are heated to help prevent water from freezing as it drains, which allows for the Allegro Bay to stay adventure-ready year-round.
