For twice/year, I'd be tempted to build a topper out of plywood and paint it black with bedliner paint. You could attach it with a bracket to the trail rail and tuck the hinged back door under the tailgate for locking. Plywood with a 2x3 frame can be pretty strong. Bracket the upper corners...
If cost is a consideration and you plan on 35 inch tires, you might consider a Sport S with the Max Tow option. The 4.10 gears will be efficient with larger tires and you can get whatever options you want and save a little $$$. Play with the "build" tool on the Jeep website.

Mesquite, TX. My music tastes are mostly late 60s to late 70s rock, but I graduated in 85. My youngest is 19 and he knows all of the words to every song on classic rock stations and can play most of the saxophone solos.

I hate those things. I'm not going to mention those to my wife. It will be her daily driver. She gets the newest and most dependable vehicles. I get them well pampered later and drive them when we are together. I'm just steering her for whatever I want as well. She won't argue about me...
