Re: Towing w/Jeep Manual i6
Depending on what you're towing it'll probably be fine. Short wheelbase vehicles like jeeps are generally less stable towing, especially on freeways or at higher speeds, or when there's a heavy crosswind. But if you're careful you'll be ok, just be aware of it. But it really comes down to how heavy your boat is.
On the plus side, having a short wheelbase is great when you're maneuvering a trailer in tight spots--I tow with a Bronco, and it's waaaay easier to back the trailer up with than a full size truck.
As far as getting a hitch installed, you can get bolt on ones and do it yourself if you want. I got mine at Uhaul, and I paid for them to install it--it wasn't too much, if I remember, and it was worth it to save me from lying under the filthy underside of my truck.
You probably want a Class III hitch, which are generally good for towing up to about 5000lbs.
