We have them in our 2004 Alfa fiver. They really worked well for 16 years. Then last September when we got back to Yuma for the winter after 2 days here a compressor locked up. I knew it was going to be a big hassle. We always liked them along with the heat pump. I usually do our own work but passed on this. Went to RV repair joint I have used for years. I asked " do you guys work on basement air"? "No we don't and I think the only place that does is just up the street" which I was also familiar with. Went over there and got a super guy in at a desk. I told him "I think the compressor locked up". "Describe it to me, yep that is the problem". "Here is the situation, bring it down and we have to jack the fiver up to get the units down". "Then I have 3 compressors in the parts house but won't know until we get your unit opened up if any of those will fit". "If one does fit you are looking at about $1600 bucks". So "I say being that some manufactures still use the units, what about a new unit". "Well Coleman (Airexcel) didn't do you any favors as when they discontinued your unit in 2010 they completely re-designed the units and you can't cross over parts from the new to what you have". I wasn't going to put roof airs on because there is no way they would cool this 40 footer. And of course at that time none were available anyway. So he said "if you were non-mobile I'd put a residential AC unit in". I came back and told my wife the situation. We discussed it for about 10 minutes and decided to retire the 40 footer from the road and look for something else for the summer as we are fulltimers. The unit went out Friday PM and on Monday morning called a guy that put units numerous park models, fivers and park trailers that are permanent in the park we used to be in and those were satisfied. He was here in 45 minutes. "We do these all the time". "What is your price, and when can you do it"? "$3900 bucks and we will install it tomorrow morning". Bring it on! They arrived 7:45AM and about 9:45 he called us inside as it was starting to cool down. 2 1/2 ton Carrier unit. We are so glad it happened. We bought a shorter fiver for summer travel and left May 18. After 6 six days heading north, I felt a hernia, so we came back dowm to the lot and opened the 40 footer back up and fired up the AC. Hottest we have seen so far has 117 and we are in here cool as a cucumber. Now for the summer travel unit, we bought another Alfa 31 footer with the same basement air. If it goes out I'll just put 2 roof airs on and be good to go.
