I second Jons reply. During my service years we had this complaint a lot. Our first question was always – “How often do you use your Washer?” A dry Washer/Dryer P-tap was the culprit 90% of the time.

On a rare occasion we would find cracked pluming lines in the bay. Sometimes the ABS drain lines would crack at a fitting allowing a bit of water to seep out causing an smell to creep into the coach when ever a vaccum was applied, such as opening a window when driving or turning on the ceiling vent. However this also causes the bay to smell but most never gave it a second thought thinking it was normal. You can usually spot a leaky ABS drain line, the water trail leaves a whit-ish residue on the pipe. looks something like corrosion on aluminum. I doubt this is your issue.

Congrats to both Jon & Tom. Now you both will have more time to use your RV’s!

I’ve not heard of age related brake line hose failures despite age. That does not mean it is not possible, but if it was I am sure there would be a lot of bandwidth associated with discussing it.

My guess is if the plastic tubng is replaced for the seat, to go back to where the air line from Prevost was attached to the air line from the seat manufacturer and all should be OK.

[Bob]

This appears to only be associated with air going to the Aux tank as the 2 main tank air gauges never move. I had Prevost check the engine air compressor/air dryer and they said it was working properly. I guess I can remove 1 air line at a time and cap that line. Once I find one that prevents this loss of air I can try to determine where that line goes. I have no access to the underside of the coach so it’s a matter of peeking around what I can see or hear and I don’t hear anything.

I have a friend who bought the snap on covers for his H Marathon and they looked great, you couldn’t hardly tell they were covers for Crapco mirrors. I think this is the correct website: Mirror Covers

Finally found the answer – YES, normal operating temp according to:

Tab: In almost ten years of seriously following Prevost coaches (and this Forum almost daily) your test drive was the first I recall hearing of an 1989 coach with a DD 6V92. Round numbers it should have 75% of the horsepower and torque of the 8V92 that I would have expected a coach of that era to have. I would guess that to be material and your experience apparently bears that out.

That said, I have for a number of year stated that the #1 best value in RV’ing today is a very late 90’s and early 90’s 8V92 Prevost with a professional conversion (apologies to the DIY crowd). While they seem to be addicted to diesel fuel, if you put a modest amount of miles on them they sure have a lot to offer. Looking at the asking prices and hearing once in a while that they trade for … you sure get a bunch motorhome for your money, especially if get an all electric coach (no propane).

Do you know the Vin# of the coach? It should be able to be deciphered to learn the year of the shell and confirm the age of the shell and drive-train. Typically a Prevost conversion is advertised and often titled one or two years after the date of the chassis shell when it left the Prevost factory in Canada.

TOM, How much for 2 PC Plates + shipping

[Bob]

I guess that’s a good Liberty instructional but I suspect that most Prevost’s have more tubing than they have copper. To replace all the existing tubing in my Webasto would require 100 feet of silicone with zero copper tubing. Not saying that either of these setups are a bad thing, only noting the differences.

Steve, I had an issue with the TPS on my 87 DDEC I coach. It turned out to be a bent connector pin that wasn’t making contact. My point is I disconnected it straightened the pin and problem solved. No programming was required but maybe DDEC II is different but I doubt it.

Your issue if you feel it is the TPS can be addressed by any Detroit dealer. Or Prevost. Or a quality diesel shop with the software to read DDEC.

[Bob]

Just curious if you found a coach or pursued a build?

Here are a couple of asserted factoids re “biodiesel”. Very much the same discussion re alcohol in gasoline for older cars and RVs:

Biodiesel is a form of diesel fuel derived from plants or animals and consisting of long-chain fatty acid esters. It is typically made by chemically reacting lipids such as animal fat (tallow), soybean oil, or some other vegetable oil with an alcohol, producing a methyl, ethyl or propyl ester.

Engine power: engine power and torque tend to be 3 to 5 percent lower when using biodiesel. This is due to the fact that biodiesel fuel has less energy per unit volume than traditional diesel fuel. … Engine wear: short-term engine wear when using biodiesel has been measured to be less than that of petroleum diesel.

[Bob]

Dan, thanks for the information, I was unaware of them. They are near my Winter roaming grounds.

I’ll share my experience on value…..(See my story above). My 15 year old coach, when traded in, cost me $12,500 in value for the 1 year change on the title. (the buyer originally proposed $25,000). Now, that value may not be significant to some, but I still consider that a large financial impact.

BTW….I still sold the coach for just about exactly what I paid for it 18 months earlier. I consider that a win.

Hi – Sadly, The Motorcoach Resort closed last year and has been converted in to storage. The url for the website is still functional, but it takes you to their storage with no mention of the Resort.

Phoenix is so large, it would be helpful to know a little more about where you might wish to be or what you might wish to do. There are quite a few choices in the region that aren’t technically “Phoenix”.

We spent the past winter in Casa Grande and found it to be just the right size. Phoenix is easily accessible, but (for example) driving to “Phoenix” from Casa Grande can take 35 minutes to Chandler, AZ or 1.5 hours to Surprise, AZ.

I’d be happy to offer any assist if you’d like, but it would help to know if there is an area, activities, or other preferences of particular interest.
