I probably got to this too late...sorry, been pretty busy.
Most campers of any brand, when they get this old, have wood rot issues. Very few don't depending on how they've been taken care of, but you have to be on the lookout. It's usually indicated by rippled/dark paneling inside the camper. Make sure to pick up the front mattress too and look underneath. Sometimes people store these campers front down, so water gets in around the front window and rots out the front edge.
Yes, you will need tie down brackets and turnbuckles to hold the camper down ideally, but you should be able to drive it home with it just held down with a bunch of ratchet straps. Just drive like 55 and not push it too much.
