Purchased class b RV 2018 American Patriot MD4 last week. Beautiful but nonfunctional- refrigerator did not work, heat was challenging, at 5’ 8” I hit my head hard several times going from van to front seat. The toilet is quite low, since I am 70, trying to getting up - Nothing to assist standing except slick walls. Loud road noise. Freeway, driving >25 mph caused tremendous creaking in the coach. We couldn’t hear each other talk, nor could we hear music. After a day of opening and closing the sliding van door from inside, needed help, I was weak. Just left RV park day early-van bed was uncomfortable. I’m sick over what I spent and the poor performance of MD4. Plan to trade it Monday If anyone knows how to turn the refrigerator on, it would be helpful. Or an e-manual for the 2018 version of American Pat MD4 sprinter. We should have tried it out at a RV park before writing the check. Sad $$$$$$$ lesson
