yep. happened to us. We were in Oregon and our front AC went out. Leak in coils. Repair wouldn't work. So had to replace. Tried to get a replacement in Oregon but RV shops too busy and said they could get to it in 2 weeks. So we waited until we got to Vegas (100 degrees!) and had it replaced. We called ahead to the shop and had the model number of the unit we wanted and gave them our credit card so they could have the new unit there when we arrived. Meanwhile, we bought the roll foil insulation and covered every window and used the back air. It kept it cool enough that it was tolerable. We also used 2 small fans. Our coach is only 34' If it had been larger I doubt it would have worked out.
