2017 garage kept Coachman Prism 2200LE with under 25k miles and under 47 hrs on generator.  Upgrades include a cell phone booster that works fabulously and an extra deep cycle battery for dry camping longer.  Mercedes Benz 3500 chasis provides excellent fuel efficiency and is extremely quiet.  Huge slide-out on driver's side extends the dinette and master bed. Storage galore both inside and outside.  This unit has been well cared for with tire rotations every 5000 miles, regular oil/filter changes, and has always been stored in my RV garage so there is no sun/weather damage.
