I don't remember how wide my JK measures, but it is on 60s with 40" Irok's. It squeeeezes through the fender on my Kaufman trailer. I'm not a fan of deck over trailers for the higher CG and wind resistance but they really aren't too bad depending what you are pulling with. A couple of things to think about if you haven't already: 1) you need a 10k gvw trailer. Your JK is probably over 6k lbs, the trailer itself will be at least 1500 lbs. and you'll always throw extra crap in too. This will put you way over weight with a 7k gvw. 2) check to make sure the tires are rated for the load! Lots of trailers come with tires rated less than the trailer gvw. 3) don't forget the spare along with a lug wrench to fit and a jack. I love the little ramp thingy as a jack. Works awesome. 4) you might think about a gooseneck trailer depending what you use it for overall. goosenecks are awesome but of course more money and there are some obvious drawbacks.
