Nice truck! As far as one can tell from that single picture, the PO took good care of it.
If you had given this information (or part of it) in your original post, you would likely have got more focused replies from the get go. As it were, your question to me looked very brief and a little odd. Since I am in a different time zone, I often get to see new posts before North America wakes up - so sometimes I get to be the "first responder".
Not all of us are used to communicate our requests or problems well in written form. After all, your question is obvious to you. It takes some training and experience to understand which information is necessary to make a stranger on the internet understand what is going on in hour head. I did not think that yours was a troll question, but maybe badly worded. So I tried to give a brief reply, to see if you came back with more information.
I still believe that the truck's overall condition is more important than what was in the back. The transmissions in these trucks don't seem to be the most bulletproof (in my local TC community, two Rams with Cummins and ATXs have made problems in the past). But if the truck runs and shifts nicely, and you trust the seller, I wouldn't worry too much about it. Just have some extra money in case something _does_ need to be fixed. At 20 years, there are plenty of possibilities. And keep the rustproofing up.
Do you have any specific camper that you are looking for?
