Newbie 74 Shasta 17 Starflyte Needing Guidance

I've never owned a travel trailer. 2 days ago I brought home this sweet camper that needs some TLC. smells a little bit. It appears that much of the paneling toward the backside has water damage and needs replacing. I got lucky and had warm weather so I used mobile home roof sealant over the seams. looks like thats what the previous owner used a while ago but there were leaks. he had it covered with a tarp when i picked it up. The aluminum front window cover frame is damaged. I'll need advice with the electrical/battery system as well. 
There is lots of reading to do on here..i could spend hours that i don't have searching for specific repair help; so much info is awesome!…

i was wondering if there was someone willing to chat over the phone, or exchange messages and pictures to help me out with my new project? i only want to do whats necessary and not a full blown restore. also if there are any rallys or round ups in or near Wisconsin? or does anyone know of a good guy to go to in Wisconsin for help with this thing? Thanks!
