Tooooo much trailer for that Jeep! no way would i tow a 29' TT with a short wheelbase small v-8 tow vehicle, even with a WDH.
another problem is the 7000lbs. tow capacity is for the Hemi-equipped Commander, not yours. the Hemi has way more horsepower than the 4.7, 100 more HP. you might be reading the hitch receiver's capacity, which has nothing to do with the vehicle's tow capacity.
i would guess the 4.7 would be able to tow 6000lbs. at best.
your trailer will weigh close to that before loading cargo, once you add the weight of options, battery, water and propane.
