Granted, I'm a bit biased but you're going to like that Jeep! I have an '89 white 2 dr. Limited (see below).
Your '91 is the first of the Chrysler "non- RENIX" XJ's. I'm not fussy about that but some people are. RENIX Jeeps have some peculiarities (electrical sensors, closed cooling system, etc.) but a lot of us like them. With it you have the 4.0 HO (high output engine). I'd have to look up the differences but they're minor … 7 HP or something silly. At the end of 1989 I bought a 1990 4 dr. black with burgundy interior XJ Laredo. I had no idea it would be the last year for the RENIX Jeeps but I didn't care. I got what I wanted and it was great!
Yours has the correct 10 hole wheels with the rivets (they don't have a name) and they look to be in good shape. Hang on to them if you like them; if not you can get a good price for them, maybe even get all of your money back! I have them on my MJ and for some reason non-Jeep people go nuts over them. That "Sport" strip is original too. It might grow on you.
I haven't slept in my current XJ but I did in my original one. I'm not tall so it was OK with a small air mattress. XJ's don't have an interior tailgate handle so you'll have to crawl out one of the front doors. You might then wish you bought 4 dr. (lol). NO YOU WON'T! About 4 dr's., the rear doors are a pain in the but to get in and out of (very small). The much longer doors of a 2 dr. are actually quite nice.
