Buying used is the only way to go. I can't afford the cost of these units new. I mean they post stickers on them like "oh yeah,, I'll get two" I mean 320,000 Yeah I'll buy two. No I rather buy a 30 year old motorhome that is in good condition so I don't have to sign over my soul to have one. Unless God finally answers my prayers and can make a decent living. until then it is used and I got my Holiday Rambler and the two AC units are no good and the generator was missing,, and replaced it with an Onan I had on hand. I did pretty good. need to buy used roof units Colaw which is 90 miles from me feels that they are made of precious metals. someday soon I hope.
