I bought one from afar. Flew there and was picked up. I was told they never used the toilet and the shower. Found out the reason why, the rubber 3" pipe between the tank and the pipe valve was almost totally split in half and was not much fun to change. $7 in price only. They had not used it for quite some time. The V10 engine block is a lovely place for squirrels to build a nest. It was packed with over 2.5 gallons of seeds and I had to take the doghouse off to get at half of them. Bloody wonder it did not catch fire. One broken light fixture, replaced with a much better LED unit. It took me two days to clean it properly.
But the deal was all done in about 90 minutes and I drove it home. We do enjoy it a lot.
If you are offered the opportunity to have full replacement insurance, consider putting it on for a few months then cancelling it. If there is something drastically wrong, as I found out, and the vehicle is a total loss, you get a brand new one.
