If you're just looking for something to tow and knock around on the trails, I'd look for a TJ 1997-2006. I think they're the simplest and most practical off road of any Wranglers. If you're looking for a little more room and comfort then some of the newer pre 2018 JKU's would be my choice. I likely would not look and any of the early JKU's as several years had the "new design" bugs still in them. Towing just about any Wrangler is a no brainer. Some differences between years but they're all pretty easy to tow.
