Thanks guys I'll look into those suggestions.
What happened was several years ago my '87 Vacationeer 11.5 was just too rotted to be worth saving so I looked for a nicer camper. I happened to stumble on the EXACT SAME '87 Vacationeer 11.5, in nice shape, at a giveaway price. I didn't even want that same camper again, but a deal's a deal.
Well, since it's the exact same one, I never got rid of the old one because it has every possible spare part for the "new" one. That's been handy several times, including providing perfect pieces for my bathroom/shower sectioning job that it needed to fit my newer Dodge with the narrower tailgate.
But ya' know, I'm tired of having a junk camper lying around!
