Oh boy.
Granted there are likely a few things from Trailer Life magazine that are useful for the Prevost experience, such as the hamburger flipper/Christmas light combo/toilet seat that the guy in Oklahoma fashioned out of Wal-mart bags.
Y'see the whole idea here with a camper is to drive it, not park it. That's where the trouble comes in.
The deal with dry rot is this: When you see it, you're already too late. Dry rot in tires, whether they be regulation, POG-approved tires or made from recycled chopsticks, rot from the inside out, so your rubber should have a manufacture date not longer than five years from the moment you inspect them. Period.
In speaking with a couple of entertainer coach drivers, they replaced them at 110,000 miles (Michelin Pilote X) as they didn't want to a) take a chance with their valuable cargo and b) would begin to see significant tread wear.
Now if someone is actively interested in taking their life into their own hands, contact the Trailer Life guy in Oklahoma who will make you some tires out of Wal-Mart bags and please report back to us how it goes.
Gosh, this posting seems ascerbic, doesn't it?
