What class of RV is this? A or C? And, whose Chassis it is, is more important for questions like this than whose House is on it. Ford? Chevy? or ______?
You posted in "C" and Ford was predominant in the mid-1980's. Fuse panel to the left of the steering column, inside, should have a little "can" flasher. I think in the lower right corner but memory fades.
