The Isuzu Diesel is a good engine, that can last over 300,000 miles with just a little care and maintenance. The TH400 is about the best light-duty GM automatic transmission, the preferred transmission is the Allison, but you most likely won't find one in the MoHo's of the vintage you are looking at.
As far as the engine, the basics, look for water in the oil, oil in the radiator, excessive smoke, oil leaks, etc. The trans, of course fluid level and color, check for leaks, and make sure it has all 3 gears, without flaring (also called slipping) between gears. The good news about the TH400 is it is relatively inexpensive to rebuild, if it needs it, while the Isuzu Diesel is very expen$ive for most repairs, other than maintenance.

be sure to see the messages in our Motorhome forum posted by Chaplain Kent regarding his recent diesel engine replacement in a similiar unit. You might find that the Chevy 454 version of these motorhomes would be less expensive to own/maintain in the long run as parts and service are so much more readily available. However if a diesel is your preference, Isuzu parts and service are available if not as easily.
The Classic motorhome can be a joy to own, if you go into it realizing that they will need attention at some point. They are a reasonably good investment as there are never many for sale and more people seeking them out...and they garner lots of attention---and give a real pride of ownership. Plus we are always willing to help, and there are many very experienced owners here.
My own has been very reliable and enjoyable over the almost 4 yrs I have had it.

I like My 1982 31ft. It has the Isuza with the TH 400 Trans. The best thing I did the day I got It.

I learned that hard way that The Izuzu is a very good, strong and reliable engine. My insurance company thoroughly researched it in trying to establish a depreciation figure for a 1982 with 60,000 miles. They eventualy came up with a figure of 20%, or that it had used 20% of its life. The one problem you may encounter is that there are not many of them out there. Make sure you have a reliable mechanic and have them double and triple check what they are putting on the engine. My mechanic ruined the engine.
Also take advantage of this forum, the few owners who have them are here. One last slice of advice I always like to give to any one considering buying a classic is to consider that the purchase price is only your down payment.
All those concerns considered I would not trade my classic for anything else rolling on the highway today. My wife and I simply can not spend enough time traveling in it.

We did not take possession of the block and I do not know if it was salvageable or not. The work was done at Standard Truck in Chicago, IL- 773-890-0000. For all I know the block could be laying in thier back lot. Good Luck

How did the mechanic ruin it? Dump sand in the crankcase, or put gasoline in the fuel tank?

Pick,
You missed THE SAGA? Mechanic either put the wrong oil filter on it or put it on incorrectly and it blew out and drained the oil...a very quick way to ruin an engine...IMHO. Hopefully someone can find the thread for you.
I can attest to the durability of the Izuzu diesels, I had an older P'UP that had over 300k on it when the body finally rotted off of it. We have a 17Kw generator at work with a 1.5 litre Izuzu diesel in it that has over 20,000 hours on it.

Rivet For those enquiring minds

If you need parts for your MoHo with the Isuzu T.D. engine, it is the same as that used in the FSR truck. This is useful if you are somewhere that has a salvage yard for big trucks, but no local Isuzu dealer. NAPA has some filters, the rest have to come from the Isuzu dealer.

Both NAPA and Carquest carry all of the filters and belts for the 6BD1T Isuzu engines. Although I have found, from experience, it is best to carry a spare in the beneath compartments just in case. As for finding a dealer they are all over. Isuzu is the largest industrial deisel engine manuafacturer in the world. Anyone who is considering purchasing one of these should not worry about getting service or parts.

The people at my local NAPAs are not exactly truck-oriented people, to put in kindly. It would be a good idea to find the cross-reference part numbers before you need them. I have been buying filters from the Isuzu/Chevrolet truck dealer here for quite a while, since NAPA can't seem to get them for me here. It is easier than the hassle, and they deliver, just like NAPA, only more $$$.
