I believe it's 20x8.5 but have to double check. Good shape, LED lights, electric jack etc. Probably 7.5/8 out of ten. Milage low, mostly used for storage. Not wanting to sell but need cash or truck. Currently has motorcycle equipment in it but will be removed this week. Body in nice shape, rolls straight. Ramp rear door. $10,500 cash or may trade for half ton truck, rat / hot rod, motorcycle or ATV
