Used Class A Diesel Checklist

Good morning, We're actively looking for a used Diesel Pusher, 36' - 40'. Does anyone have a fairly comprehensive Checklist or procedure suggestions for checking out a used Coach ?

Blackstone Labs


I have used both of these companies for used oil analysis, and it is critical to get a sample of oil, engine/transmission to make sure that you are not buying very expenisve problems.

A used oil analysis will tell you exactly what condition the beast is in.

Thanks Rough Road,
Many of the used ads say that they've just had a service including an oil change. How much does the engine have to run before an oil analysis will detect problems?

Michguy, I am told by smart people that for a coolant check the minimum is 100 miles and for serious wear the minimum is 200 miles, the general consensus is that with 300 miles you get 'good' numbers.

Seems like the perfect argument to have the dealer let you take it for a real long ride-the easiest way is to spend about twenty bucks for a sampling pump. With one all you have to do is either order long sections of tubing,-tell the lab what type of vehicle you are sampling and I am certain that they will send the proper length of tubing- I find that four feet works with any type of vehicle or just go to a hardware store and buy 12' or so of 1/4 inch of the hard white tube. Only trick is to be certain that you do not draw from the bottom of the pan, it will take you about a minute to get a sample, about a week to get the results back.

The procedure is quick and clean; make certain that you have the miles on the oil, warm it up, shut off the engine and let things drain back for a few minutes, remove the dip stick, insert the somewhat stiff tubing into the pan through the dip stick tube until you just feel it contact the bottom of the pan, pull up the tube about two inches, insert the tube into the handpump, attach the small plastic jar and give two or three pulls. It wont' feel like anything is going on but in a few seconds you will begin to see oil coming up the tube and collect in the jar. When you have it to about 1/2 full pull the tube out far enough for the vacuum to break and let the oil drain out of the tube-remove the jar, cap it off, remove the tube from the pump. I always have a cloth around my had as I pull out the tubing to clean off any oil. Be sure you do not reuse the tubing.
Then all you have to do is put the jar into the mailer that is provided to you, take it down to the post office and send it in.

Of course gloves are nice.

It has saved us from one very, very expensive mistake-with the engines in your class of rv the cost of replacement would have to be easily in the $15,000 range.

When we shopped for a used DP, we were only interested in a No Slide DP, and that somewhat limited us to mid to late Ninties models. Finally settled on Sarfari, which we ultimately bought (for a lot of preferential reasons). I found a Yahoo User group for the Safari's and they have a downloadable PDF (6 -7 pages long) that is a Motorhome Checklist for buying. It was a great tool for us to sift through a lot of coaches. The link for the checklist is http://f1.grp.yahoofs.com/v1/0JCOTGk...eck%20List.pdf and I believe you have to join the group to get access to it, and the homepage is http://autos.groups.yahoo.com/group/...yguid=11485381 . Great bunch of folks there that helped us quite a bit, especially "Guidence" on "Pricing."
