Looking to purchase used 1992 WB40

[mbrund]

I am looking at purchasing a used 1992 WB40, I was wanting to know
what things to look out for on this year model. I was told by the
current owner that one of the Primus heaters is a little flaky, and as
I understand by reading at various places that this should be of
concern since there is only one place to get parts. He said he did
not know what the issue was as it works sometimes, and does not
others, but the other unit works all the time. New fridge. Cooktop
and washer/dryer have not been used during the current owners 10 year
term.

What other items should I look for while inspecting a coach of this
year model that might be a big ticket items?

Coach has ~140K miles ~3000 hours on 8V92, 4 years on tires (kept
inside), 4 years on GEL cells (low batt charger plugged in while in
storage).

Thanks,
Michael
