Possible Big Repairs, Used Motor Home

To me, I consider a to 2 to 4 year old DP to be almost new.

I purchased my 02 Newmar Dutch Star DP (see below) in early 2010. Put on 32,000+ miles since then, for a total of 93,000+ miles currently on the odometer. No major problems, only run-of-the-mill stuff and standard maintenance issues. Only major problem was due to my fault for reassembling a major component (hydraulic cooling fan motor) incorrectly (even though I knew better how it should have been done correctly).

30,000 miles in 14 years, oil, filters and tires .. Cummins 8.3 ISC Allison 6 speed. Spartan chassis.

One major PITA, a loose ECM causing the engine to quit as it felt like it. more trouble shooting than money spent.

Our Cummins/Spartan/Allison is 10 years old and no engine/transmission problems. 70,000 miles on it.

Engine and Tranny are the big ticket items for sure. Get used samples of all fluids, engine oil, coolant and transmission oil. Hydraulic oil, too, if hydraulic fan cooled. Results will give you a snap shot of condition. Make it a condition of sale. For peace of mind a warranty may be worth it. Most of the house stuff is no different than your 5th wheel unless your MH has an Aqua-Hot. That is also a big ticket item.

I was pretty nervous about those items as well. We went from Travel trailer to Class A. Make no mistake you need to have some resources around, cash, warranty or credit card. You should also plan on ~$5k to make it yours or for incidentals. Things you didn't find on the walk through. Most RV elated engine problem are due to poor maintenance of the coolant system.

IMHO tires are the telltale, anyone who goes cheap on the tires skimps elsewhere, too.

Agree with most of the replies. Look at engine, tranny and chassis maintenance records, any service you can not verify, have it done or DIY. Oil, chassis lube, filters (Engine air and oil, fuel, coolant, air cleaner, Air dryer etc)
At 2-4 years years unless it has been grossly mistreated the problems should be minimal. If the interior looks neglected, the chassis probably is also...

After eleven years on my ISB Cummins I had to replace my turbo because of electrical problems. Other then that I replaced a alternator and a transfer pump the latter two under warranty. The turbo went at 88,ooo miles and cost around $3800 total. Other then that repairs have been very minimal and none to any drive train parts.

With this in mind my earlier comments about an extended warranty still apply. I would get one and sleep easy!

If I buy a 2 - 4 year old used diesel pusher motor home (to avoid huge front end depreciation), what are the big things I might get hung with? Motor repairs, transmission repairs?? How much might that be, how to avoid it?

One must know how handy you are, lots of stuff can be repaired or replaced by the owner.

2-3 year old diesels I would not expect any big repairs after the infant mortality is over. keep oil and fluids full they should run the life of the coach. same with the transmission.

Coach appliances are the luck of the draw. they can fail at any time

The coach is totally the quality of the build, and if the manufacturer is still supporting the unit.

Monaco, Beaver, Safari, and several other companies built some wonderful units, but you are at the mercy of the industry to support them in a major repair. but when they are in good condition they can be supported by the simple appliance replacement and or upgrades. keep them insured, when a major accident occurs grab the money and find another.

Take it to a certified engine and transmission facility and they can check your repair history using the serial. Number. Also can do a plug in diagnostic history of what's in memory. Check refrigerator fall any recall. Go to chassis certified dealer to have them check for recalls.
