Looking for XL40 with Series 60

Thx Peter!

Actually, although I may be in a minority, my experience on two coaches is that in dry weather exposed to sun you will have a problem cooling a coach with Cruise-Airs parked or moving at anything over 95-100F ambient. In humid weather, their performance is a little better.

Geo, I mentioned the Vantare and the Liberty sound boxes for exactly the reason you mention as examples of excellent generator sound control. When my generator is running and I am running a Cruise air or two I do not even hear the generator.
Peter’s answer regarding Cruiseairs is on the money except over the years the Cruiseairs do much better while the coach is in high ambient temps while the coach is being driven.
Our 87 Cruise Airs would shut down due to inability to deal with the heat radiating from a highway. My 97 the Cruise airs worked well while driving. I have not yet tried them on the current coach. But the cooler the air passing over the condensing coil the greater the efficiency will be. Roof airs are not dealing with very high condenser side air temps because they are drawing clean, cooler air off the roof.
-
So presumably then, with OTR, CruiseAirs (if fitted) & ‘hot highways’ is a non-issue?
-
Don’t throw in the towel on a coach you like just because is has Crusiairs. Like Jon noted, the later coaches seem to do a better job on Cruisairs not shutting down. Mine has not had that problem and I don’t have OTR, although earlier coaches I had did shut down while driving due to road heat. I’ve never had one shut down while parked due to heat, but I have no experience in the desert southwest in the summer.
-
I think the best would be roof airs and OTR , if the OTR takes a crap you can use the roof airs , that is if you drive a lot , but as Tom and Jon said the new cruise airs do good going down the road in high heat!!!!!!! I am not sure of that have never tried it in high heat and for all day when driving!!!!!!
-
When you guys say “the new cruiseairs” are you referring to Prevosts built after 2000?
-
Joel – thank you very much for your AZ input!

I just wanted to jump in here on the cruise air and roof air difference. I have had a prevost with cruise airs, one with Vantare RVAC and 2 cruise airs and my third prevost has roof airs.I do want to point out the fact that the cruise air coaches are quite a bit noisier when sitting outside the coach around the area of the entertainment bay, say watching TV or just sitting out under awning. Plus you can get some unwanted heat being discharged in this general area during summertime from cruise airs. Just my 2 cents worth.

I have also noticed the extra noise and heat outside with cruise airs on our Liberty. Our Legendary had roof airs, and they were louder inside than the cruise airs, so I guess it is a bit of a trade off…

Hi Kurt, I just want to tell you that American coach is a viable alternative for you . I have a 2002 American XL2 with roof airs and 6 batteries (from Tom of course) and very few electronics and we love it.y are less expensive than the better known brands but The quality is still good.
-
Bill and Mark – thank you for the insight! Definitely tradeoffs between two.
Red – you have been the most help of all and I will be eternally grateful! I have funds immediately available – you just tell me when and where you want me to pick up your coach! I promise to take very good care of it. Seriously, there was an American still advertised but already sold. We liked it and would have snapped it up if available.
You all are a wealth of knowledge – thanks!
Kurt

There is no perfect coach house A/C system. All of the flaws and benefits have been pointed out above. The comments about noise outside along with heat discharged around the entertainment center is absolutely correct regarding Cruiseairs, and the noise inside the coach with roof airs is also correct.
Regarding how well Cruiseairs work when driving, my 87 coach Cruiseairs would shut down when the ambient temps were in the 90s. I know that because my OTR quit working so the Cruiseairs were my back up plan, except they wouldn’t work due to the heated air radiating from the highway. But my 97 coach Cruiseairs did not shut down under the same conditions. I haven’t had the opportunity to determine if the current coach Cruiseairs work but I assume they will while driving.
One unmentioned issue is the number of units. My experience has show 3 units will work on a 40 foot non-slide coach. A 45 footer non-slide is borderline mostly because the glass on an XL is not double pane. I would be concerned if any 45 footer had only 3. Add slides to a 45 footer and in my opinion 4 units would be required.
Why so many when I rarely run more than two? First if the inside temps get too high it does take a lot of capacity to cool the coach down to comfortable levels, especially if it has gotten heat soaked. But maybe more importantly is for back-up. If one fails you are left with only the remaining units and in a lot of instances in the summer they are best described as barely adequate. If you see entertainer coaches it is almost a certainty they are going to have 5 units because they have ample capacity and backup.

Kurt, I agree with Red that American Coach conversions are good for boondocking. Apparently American used both roof airs and Cruisairs. Mine has 4 Cruiseairs, which I really like. They don’t shut down while driving, but I did have that problem on my ’90 Country Coach XL40. I don’t have OTR, but my MCI has super powerfull dash air, effectively 1/2 of the OTR system, so that may make the difference. As Joel noted, Cruiseairs do have a hard time cooling the coach while parked on shore power if the temp exceeds 100. We don’t have slides. With slides increasing the interior volume I think it would be even worse. Not sure if roof airs can do better at temps over 100 in an RV conversion, but I’ve been in entertainers with 5 roof airs that were ice cold at 105 ambient. Noisy, though.
