Purchasing a 1996 Jayco 1006 pop up

We are going to be purchasing a 1996 Jayco 1006 pop up tomorrow. We already have a 5th wheel, but wanted something smaller for ds and his friends, or for when we want to go to state forest campgrounds. We've never owned a pop up before, so I wanted to ask if there is anything we need to look for before buying? The tires look good, I don't notice any signs of leaks, the floor is solid. We will go through the camper again tomorrow and the owner will show us how everything works and how to fold it up, etc.. I just want to make sure we don't miss anything important.
