Keystone RV Alpine fifth wheel 3700FL highlights:
- Underbed Storage
- Bath and a Half
- Kitchen Island
- Front Living Area
- Hitch Vision
- Heated Basement Storage
A full rear bathroom creates a master suite in this fifth wheel! The private bedroom has a king bed slide with storage underneath for extra blankets, a chest with TV, and access to the full bathroom which has a dual sink vanity for two to get ready at once, a shower with a seat, and an area prepped to add an optional stackable washer and dryer. The half bathroom is by the kitchen so you can quickly get back to preparing your delicious meal with the three burner cooktop and kitchen island then enjoy your meals at the free standing dinette. The front living area has a front entertainment center with a 40″ fireplace and 50″ TV with overhead cabinets to store your movies, as well as opposing tri-fold sofa sleeper slides and Thomas Payne theater seating with heat, massage, LED lights, and a USB charging station.
Luxury is not an option, it is a standard with each one of these Keystone RV Alpine fifth wheels! A 100″ wide body construction, almost 7′ tall slides, high ceilings, and panoramic frameless windows create an open, residential feeling. The Tru-Fit slide construction is more durable and minimizes motor structural stress, as well as resists leaking. Exclusive 12V color-coded wiring is different from conventional RV wiring in that it is easy to trace and clearly labeled to help savvy owners with DIY diagnosis/repair and helps dealer service techs troubleshoot/repair quickly which saves you time and money. The in-floor heat vents run straight through the unit and are typically positioned in low-traffic areas just like in your home for a more efficient air flow, plus it helps to keep the cabinet storage space.
