Thanks, everyone, for the welcomes! To answer some of your questions, there are some hills, like the coast range between us and the Oregon coast, or the Cascades if we head towards Mt. Hood area. We are close to sea level. As far as budget for mods, probably don't have too much, hoping it will be ok "as is". But if needed, I can do bolt-on type mods myself. The dealer showed me some research he did about adding mods, since he was thinking about buying this truck himself. I forget the name of the company he contacted, was somewhere in the midwest I think. Most of them were in the low hundreds. As for experience in towing, I have none, other than small utility trailers. Will probably do no more than 3-6 trips per year, mostly within 100 miles of us. As far as I know the truck is all original. As I said in my first post, there was only one owner before us. According to a friend I showed the truck to, he said it looks like the guy towed a slide-in (term?) fifth wheel, as there is a separate plug in towards the front of the bed, on the side, and there are what look like square hitches under the bed on the sides towards the front also.
