I was a little wary of towing my new camper with our JGC but I figured I'd giv'er a rip and see how she did.
I have an '06 with QDII and the 4.7. The only mod I have is a Timbren SES kit to help her ride level with my trailer in tow. My camper is a 30 foot travel trailer that weighs 5350 dry and tongue weight of 725. With all of our luggage and food I'm guessing she was around 6-6100 lbs.
I have a weight distribution hitch (reduce tongue weight) with reese stabilizer and anti sway bar as well. Of course I have installed a electronic brake controller for the trailer brakes as well.
When hooked up she sat almost dead level and off we went. You can definitely feel that she's pulling a significant amount of weight but everything felt very stable. In tow mode I ended up just using the automanual because the shift points are ****. I was able to maintain highway speed (65) for the trip even up decent grades when shifting accordingly.
The fuel mileage was terrible as expected. I got a whopping 8.2 MPG over the hour long trip.
I do know my next mods will be a tuner, intake, and catback for a little more umph. Other than that I was surprised how the lil 4.7 did with such a load and four people inside. The trans didn't seem to struggle or run hot and there was no tranny smell whatsoever.
The best part was the day we we pulling out a man drove by in an F-150 and saw me hooking the trailer to the Jeep and said, "You're towing that F'n thing with that Jeep?!?" I replied yes, and he continued, " ******* it I wouldn't have traded the Wife's Jeep for this flippin' truck if I thought it would tow my camper." He had the same camper as me and traded his 07 JGC in for an older truck with more miles. Hooray for me and my lil 4.7.
