This rig has been upgraded with a 15,000 btu A/C unit in the bedroom that runs off a 20 amp outlet on shore power.  Everything is in good working order.  Tires are only 1 year old.  Less than 25,000 miles on the engine and less than 100 hours on the generator. We are no longer snowbirds and unable to use this rig to the fullest. We are the second owner in Phoenix and the first owner was in Tucson. PM me with questions.
