Congratulations, Todd!!!

The place sound awesome. You guys are going to enjoy it immensely.
I wouldn't get my hopes up too high on the "nothing going wrong with that old mobile home". Keep the trees cleared away, set tons of mouse traps, and make sure you drain all the water real well, and you shouldn't have to fix too many pipes every spring.
Camps are a lot of work, but you and the boys have lots of hands. You'll all do just fine.
