Description
Tiffin Motorhomes Allegro Bay 38 AB highlights:
- King Bed Slide Out
- Shower with a Seat
- Triple Slides
- Overhead Bunk
- Residential Refrigerator
Head across the country in this luxury coach for nine! The dual opposing slides in the main living area will provide you with tons of space to stretch out once you park, and you'll find seating space on the two sofa beds and the booth dinette. The chef can whip up a hearty meal on the three burner cooktop with a convection microwave with an air fryer, and the Expand-An-Island will come in handy when they need extra counter space. The private toilet and sink are right across from the shower so two people can freshen up at once, and you'll love having the rear bedroom all to yourselves. Here, you'll find a king bed slide out that can be optioned out for a queen, a large wardrobe with a bank of drawers, plus an optional washer and dryer if you choose to add. The interior is inviting, but you will also love spending time outdoors under the power awning with LED lights as well and an optional exterior TV.
Each Allegro Bay Super C diesel coach by Tiffin Motorhomes sits on a durable Freightliner Custom S2RV chassis with an impressive 360 HP Cummins B6.7 engine for power you can feel. You will appreciate smooth handling thanks to the Trac-Tech full-time NoSPIN differential single rear axle and the automatic traction control. There is a manual release valve for the rear air suspension for added convenience, plus a 12,000 lb. towing capacity that will allow you to bring along the family car or even a horse trailer! This coach includes a Truma AquaGo Comfort instant water heater, AGM extended cycle house batteries, an 8.0 Onan Quiet Diesel generator, plus many more top of the line amenities. You will also love the Generation 3 paint schemes, an exterior ladder, plus optional Starlink prep in the sewer bay that will give you the option to have internet while you're away from home!
