Re: 1988 Georgie Boy Cruise Master L.M. (need Help)
Not a Guru, but I'll tell you what I can.
We recently (June of '07) purchased a 1989 GBM 32' Cruise Master.
My 1st stop at the parts store was quite enlightening. After telling the counter man what year and engine, he quickly determined that ours was built on a Chevy P-30 chassis. I also managed to verify my chassis with a local RV dealer.
After that, finding the right parts was relatively easy.
Since it is a 460, I gather it is gasoline, not diesel. If you go to
www.oreillyauto.com and start "shopping", it will ask you to select or add a vevicle. Pick the year, the make (based on the engine), and then one of the stripped chassis. If I did it right, yours is built on a Ford F53 stripped chassis (with the 460). Please verify this by some other means, too.
As far as repairs, you can do almost anything yourself, as long as you know what you are doing and have the tools. If you are not sure, have someone else do it. I have been a shade-tree mechanic all my life, so I will repair almost anything. Even rebuiding an engine is okay with me (done 2 of them).
Since we got ours we have done steering work (idler), full brakes (master cylinder and front and rear pads), tune-up and carb work, under-dash electrical and even some minor body repair (separted corner) in the driveway. Then took it for a 2700 mile road trip without incident.
Dig in, do what you can and don't be afraid to ask for help. Great group here, they helped me alot in my questions.
Have fun,
