Purchaced a used 1992 TM.

I bought the 26foot 1992 TM. in Harrisburg PA. I have been wanting one and it went on ebay and I decided to bid. I'm new to the site and the trailmanors. I wanted to know what I should check out on this older unit before I start using it this spring/summer. I did not find any manuals. When I towed it home I lost the tail lenses(no big deal). Its in decent shape for its age. Needs a little cleaning! The battery/lights work but haven't checked much else. They claimed the previous owner said everything worked(you know how that goes). It has been winterized and I don't want to check the plumbing unil the spring thaw. The place that sold it leak checked the gas. Thanks for any input. So far I like it and it towed great with my Ford Excursion (4hr trip home). Thanks JOHN
