I am looking at a coach this Sat.The unit is a 30' 1991 Breakaway.I have the pdf inspection sheets(thank you Dave). According to the owner,this unit has not been driven in three years. Does anybody have any other suggestions as to what I might be careful of in terms of possible major expenditures or anything else.The coach sounds "good on the phone",.....but.All input accepted.

Bill NY provided a good discussion on how to approach a coach with low miles:

Pros and Cons of a low mileage coach

While his discussion involved a Regal, anything that's been sitting for three years would require similar attention. I'll leave further explanations to those with more knowledge then myself

You're most likely better off with one with higher miles that has been used regularly. This one may seem like a good deal up front but the potential component failure rate is much higher here from what everyone seems to say. They just don't sit well at all - especially diesels. You may have a difficult time getting it home unless you live in the area.

I talked to Mr. Merkey several weeks ago about his coach and exchanged a number of emails with his son in law, Bill Harrington. I believe one said the coach had been started every couple of months to circulate the oil.

Started and moved or just started?

I just received a message from Mr. Merkey, He said that he starts it and runs it every 3 or 4 week and exercises the steeing and such but it is on blocks so it does not move. He said has had added a few things like an Allison transmission cooler.

Sadly, starting a diesel and running it at cold idle is very hard on the engine. Running it warmed up at load (as in travelling with it) actually causes very little wear comparatively.

Another issue with an idle coach is all the things that are going wrong that the owner doesn't know about because he's not using it to discover them.

This has the potential of becoming a "Project Coach". However, bought right, it's still a Barth...
