I, too, have found the JT (JTR, in my case) to be an adequate towing rig. I've pulled my GeoPro 19FBS literally thousands of miles in the desert, the mountains, and in the piney woods w/o any problems at all.
That being said, I don't pull around a behemoth, 18-wheeler-sized travel trailer...
Absolutely NOT an off-road trip, but fun nonetheless: I drove over to GIbsland, LA, to the Bonnie & Clyde museum there and then drove south of town to the site of their deaths. I thought I'd share the pic of the Glad next to the marker.
I really like it. The 190W solar panel is now standard, as are the "off-road pkg." (translation: it's lifted a bit) and the 12v compressor fridge. The trailer itself is an easy tow and is comfortable. I've enjoyed it very much.
I would LOVE to make this trip. What would be even more fun is if a group of us got together and did it. I used to be in an Audi group that did GTGs every year...talk about a blast! The added benefit is that you have a backup in case of a breakdown.
It’s the Rubicon, so it does have the 4.10. I don’t think the Rubis come with MaxTow, though. Mine has the standard tow pkg — receiver hitch, that stuff.
