Asking price is $6000. It needs a new fridge, new canopy, new tires, windscreen cover on front is missing, and windscreen is cracked (but not leaking.) minor things like clock doesn’t work. A/c and heat work. The person using it for the last couple years has only used it parked under a metal canopy at their parents house, so they do not know if the sewer system works, but they believe that it does. They bought it a couple of years ago. Is this a good deal? How hard is it to find needed parts?
