I'm not sure of what your question really is tow the jeep with a recreational vehicle or tow your recreation behind the jeep??
I have a 6X10 high box covered utility trailer. Tow capacity of my jeep is 3500. Limit of the trailer is 2900. I have probably had it close to that limit. I take mine camping for weeks at a time. Kayaks on top, bikes, SCUBA and all kinds of camping gear and kayaking gear inside including a foldup kayak trailer inside. The jeep grunts a little, the gas mileage goes down to about 10mpg but I always get there. Some inclines on the highway I've had to shift down to 4th to maintain above 55 but IMO I figure that is part of the equation when towing something that heavy with a jeep.
