Very nice Rip, is this something you were sure you could tackle when you first started or was it a learn-by-doing type thing?....(I work on my own things too if I have the chance...boy is it treacherous waters telling the g/f you took apart her console to get a few more watts out of her stereo system and thus she can take your car to go shopping
) but overall it looks pretty good...
I knew it had some previous leak issues, but I did not think they were extensive as dry rot. I was scared ship-less once I started tearing it apart. To prevent the wave of panic setting in, I sat down and drew up a project plan, in 3 phases. That calmed my nerves, and I began a parts list, then the confidence kicked in. It was nice talking to someone who has done it before too!
RPM, Holiday Ramblers are the best on the market IMO, used or new. My 1973 11.5 Truck Camper was the last truck camper HR made, and we were still using it up until last year! Built like a bull, you'll get many years out of it.
Now, did you specifically go out and shop only HR or did you stumble upon it and now your a fan boi of HR?

One other thing, aluminum frame and skin does not make you exempt from leak issues. If you have windows, or seams, that's where your troubles will be. Fiberglass over steel frames don't leak either, except around windows or seams, as was in this case (the large front window up front which is now bye bye)
