Forest River RV Berkshire XL Motor Home Class A - Diesel

Around every turn of a Forest River RV Berkshire XL Class A diesel motorhome is a sophisticated décor, sumptuous hardwoods, and an unsurpassed attention to detail! They are powered by a Cummins ISL turbo diesel 8.9L engine and held together with a V-Ride rear suspension, a Tru-Brace anti-camber support bracing, and a Freightliner XCR raised rail chassis.


A passenger seat workstation lets your co-pilot get some work done as you drive and a 10" dash radio with color back up and side view cameras plus navigation will help get you to your destination safely and on time. The full body exterior paint is sure to turn heads as you travel and the 4-point fully auto hydraulic leveling system will have you set up at the campground in no-time! You will also love the interior with its polished porcelain tile throughout, hardwood cabinetry, roller day/night shades, and more comforts!
