I have joined a new world that I have no knowledge of whatsoever... I just purchased a 72' Compact Jr and have a lot of work to do, things to do and replace. I purchased the Compact Jr from a local in So Cal I am a contractor so I am use to getting my hands dirty. If there is something I should know from the start please let me know. I will be on this site daily looking for new things to learn.
Welcome Jeff - You are already well started on road to further knowledge about FGRVs, by searching out this web-site. There are many willing participants, just waiting to hear your queries. Just ask !, and then listen !
Yep, as mentioned, start from the bottom up and be sure everything is safe and secure, check tire age, inspect and repack the wheel bearings and attack the floor. It's also a good idea to replace all of the exterior lighting wiring at the same time.
Here's some pics of my similar Compact-II rebuild. If you would like to see it I am in Riverside, but I don't expect to be back home until early October, but feel free to ask lots of questions.
