Amazing super clen "super C" !! This Dynamax Isata IF270 is on a 2015 Ford F550 4x4 chassis with a 6.7L powerstoke diesel, 27k miles, This Rv is the perfect size at 28'2" long. It has no problems cruising at 70-75 mph while pulling a loaded trailer. This unit has all the goodies, full paint ( shines like new ) aluminum wheels, Continental HDR tires with good tread. I just had new rear air suspension installed with a new compressor. Also just installed new coach batteries and two new solar panels ( 200 watt ). Has an inverter, 2 tv's , one outside and one inside, one hydraulic slide, auto start diesel generator, auto leveling, rear view and side view cameras, 58 gallon fresh water capacity, black tank flush, exhaust and intake mods for better mph , power and reliability. Interior is incredible too with real cherrywood cabinets, porcelain floors . dual shades on all windows. fridge/freezer is 120V or runs on propane. convection microwave, ducted A/C and heat. I have really enjoyed this RV over the years . It's great for boondocking ! but it's gotta go because i bought a new unit.
