Thanks, everybody, for the replies and helpful information! I had the truck looked at and was told it should be okay to haul it- I have overload springs, and I found out the camper was only a little over 1,000 lbs.
I drove about 2 hours away and picked it up. Bringing it back was a bit scary (I definitely need mirror extensions!), but we made it over the bumpy roads in one piece. ;)
All the jacks worked great, they had the tie downs, and I checked the electric and everything powered up. It does need a water tank, but that shouldn't be a huge $ issue. There didn't appear to be any water damage, and it is in decent condition inside and out.
I am starting a new job next week, and when I have the finances, I'm going to do some rebuilding... maybe I'll start a thread- I have some cool ideas :)
Thanks again for explaining where to find information, for providing a lot of it, and for the general help/tips. I'm excited to be a part of the community, and when I dive into this thing, maybe I'll learn something so I can help some other newbie in the future!
