Shopping for a Prevost

[Gil_J]

It seems that the XL-II panel failures are most prevalent with coaches that are subjected to long stays at the beach. It very well be the salt spray (just guessing). I know the one picture I saw showed what appeared to be corrosion on the frame member on the surface that mates with the side panel. It's impossible to tell is this was from the environment, poor application of the corrosion inhibitor, or an interaction between the adhesive and the corrosion inhibitor. I wonder it anyone has had rivets and cover installed as a precautionary measure?

Air conditioning systems generally run off of 110VAC or the coach's engine. Dash air runs off the engine and only has dash air outlets. Over the Road Air runs off the engine and is intended to cool the entire coach when going down the road. Prevost's is probably overkill given it's intended to cool an all windows coach with over 50 people inside. Country Coach developed their own OTR Air. Much smaller than Prevost's, does not take up a bay like the Prevost OTR air, and with the dash air running it will cool a coach. 110VAC air includes roof air, cruise air, and basement air. Roof airs tend to be a bit noisy and may or may not be ducted. I have 3 roof airs and seldom use more that 2 during the day and 1 at night. Roof airs should be capable of cooling a coach while driving if you don't have OTR air. FWIW, traditional plastic coaches don't have OTR air but rather depend on roof airs, so it's safe to assume they should work on our coaches as well. Cruise airs are split systems, so they are quieter. They do take up space in the bays and I've been told are not effective in hot climates when driving as an alternative to OTR Air. Basement air is really nothing more than what's traditionally installed outside of a mobile home. It's a self contained air conditioning system like a roof air, but larger. I'm not sure basement airs are being installed anymore. Roof airs are norm in the greater RV industry.
