I purchased this generator 3yrs ago NEW to use with my pull camper and only used it 1 weekend of camping with maybe 20 hrs on it at the most and the rest of the time it has sat in my storage shed covered up.I purchased a motorcoach with a built in Onan generator so I have no use for it anymore.It is 6250 max watts and 5000 running watts...The unit is in EXCELLENT CONDITION and starts up on the first pull......It has a Subura engine on it and NOT a Briggs & Stratton engine.I also purchased a NEW pair of tubeless tires for it so you do not have to worry about getting any flat tires.
