This was bought brand new , already two years old from the dealer, lived in for six months over two years. Still brand new, in every aspect. The rear a/c has been replaced (3) times, keeps trip breaker, finally had another breaker installed, (1) 15 amp breaker for each a/c. Bedroom a/c. Makes alot of noise, but cycles with air. Rear a/c blows only when it blows cool air, more to bathroom and bedroom (which need to be directed at rear) I have spent $300 a month just on power, with two a/c running, TO GET THE SAME TEMPERATURE INSIDE, AS IT IS OUTSIDE !!! MY winnabego 37RD . SUCKS, SUCKS, SUCKS, I still have the onsite Warranty but hasn't been fixed. I've had several people here to try to fix it (20) times after all the problems the new unit now has E5 code. It still doesn't cool down enough to have the a/c cycle to not freeze up, and actually work like designed to work!! Alot of money for what's supposed to be top of the line fifth wheel, I wouldn't ever buy another winnebago, unless someone could actually fix this a/c or I (REALLY CHECKED OUT THE THE A/C ON ANOTHER ONE) but then again ,I would probably look somewhere else first !!!!!!!!!!!!
