RV Repair: 1985 coachman motorhome, coachman motorhome, home depot

Question
We recently bought a 1985 coachman presidential motorhome as a fixer-upper, but we have having trouble finding parts for it, Do you have any suggestions on a website or catalog?

Answer
I always shop at autoparts stores for any mechanical needs.   Rockauto.com is also a good site.  

I always shop at Home Depot for interior and exterior repairs.  Your RV is older now and it does not have to be OEM to look good.  You can find better quality parts and supplies at the Home Depot.
