"select55".....Once again, you have no clue what you're talking about. Yes, mine has vented doors and IS cooling off my DEF and large exhaust. We all know that the temperatures are thermostatically controlled. Heck, even you figured it out!

I didn't say they were there to cool while driving. The DEF system cooks after stopping and needs to cool. Mine even has venting on the passenger side for the DEF.

Your little post to apparently correct me failed.....because you don't have a clue....just another blowhard.

Our coach doesn't have vents, so just open the rear engine hatch to cool off the sleeping quarters before bedtime, altho the new coaches do have vents due to the elevated engine enclosure temps caused by larger mufflers and the DEF usage.
I have been considering dumping the muffler and just going for a straight pipe..... but then again someone would likely have a problem with doing that.... still a kid at heart.... straight pipes on a flathead ford....!

Lots of discussion about the Source Engineering wax valve "upgrade"--my understand is that it was primarily designed for a Monaco application. Reason I ask about this--my problem was not with an electronic controller failure but with lack of interface between my OEM wax valve and the need for dash A/C condenser air flow. If your condenser is located on the radiator stack, how will the S/E wax valve control A/C condenser cooling needs?

"Old Scout".....Call Jim at Source, he and his business partner are brainiacs and will answer all your questions. I spoke to Jim while at an Oregon FMCA Rally and their wax valve sounds pretty bullet proof and if I recall, variable speed, not just high and low.

Yes, Jim is great. It was around 700.00 for the parts and I did the work myself, but I am glad I did it.

Appreciate but my interest was curiosity only--I was wondering if some one knew the answer to the A/C interface issue. Was able to solve my OEM wax valve issue my moving the condenser off the stack and adding electric fans. Always hated the idea that the dash a/c was dependent on a large engine fan for cooling. Having to re-route one of the a/c hoses wasn't much fun but the results were exactly what I was hoping for. Superb dash a/c performance with no reliance on wax valves or electronic controllers.....
PS--I think the generic wax value provide variable speed control by design--as the radiator warms and the internal wax melts, the valve gradually allows more fluid flow thru the control hoses and fan speed increases......
