We purchased our 398-M in March of 2017..It is now December 2017 and in has been in for repairs after every trip that we have used it. At this time we have used it 6 times. It has spent over 6 months total in the repair shop. We have had problems with the refrigerator, heating system, air conditioning system, charging system, trim falling off inside, lights falling off outside, shower leaking, rear beds fell off the walls, blinds fell off, tires blowing, power switching from generator to battery power, and any more items. We would not recommend this product to anyone. We spent almost a $100,000 and the dealer knowing the problems with ours will only give us $50,000 for it. They know that it is a lemon and do not want it back in their hands. They said that they could not resale it due to all of the repairs made and it’s repair history.
