Condition and records indicating proper maintenance are important of course but just from what I can see that coach has a lot going for it. One thing that leaps out is it does not have those troublesome air/electric ZipDee awnings.

Good Info,

I will check those items, especially the bushings, the radiator has never been out. Thanks Prevost service!

Temperature Differential??

Isn’t a 20 degree temperature
differential between the between the intake air and and the cooled
air coming out of the evaporator about right? That’s has been my
understanding for a long time.

80 degree air going into the evaporator
should be about 60 degrees coming out.

75 degree air going into the evaporator
should be about 55 degrees coming out.

You get the idea.

As the coach gets cooled the intake air
gets cooler and cooler as does the air coming out. Systems with any
more temperature differential are more likely to have ice form on the
evaporator coils.

Maybe some AC experts will chime in.

Low pressure and high pressure sensors. If 63 what was the differential. I have new compressor, dryer and expansion valve as well and the best we got was 59 with ambient being close to 80.

Thanks for the replys on my tow plug. Also thanks Buddy for taking the time to send photos , that helps. Steve

Couple of questions. Does the replacement for the Atwood bolt up as a direct replacement or are there snags? I am mainly concerned about the 12V control wires that Atwood uses on the front of the unit. (Kuuma)

Second, regarding the Shurflo 2088’s that CC used forever…. I have replaced the heads several times because the diaphrgam fails or leaks but also the pressure switches. Cheaper for me to replace the entire head and you can get them in two days from Amazon.

I replaced one of my Atwoods (EHP-10) a couple of years back, the other was fine. Since Dometic has purchased Atwood I am concerned. First, that model is no longer made and second…..well, you be the judge. Remember the Fantastic Fan was guaranteed forever….that is until Dometic bought them…..

Finally the CC use of QEST butyl pipe and fittings. This is a PITA. Has anyone adapted newer hose? I know that QEST was one of the first but, for openers, I loaned out my set of pliers that set the infamous rings a couple of years back, never to be seen again and I do not want to spend a hundred bucks on pliers for obsolete plumbing..

Thanks in advance
