Last week I towed a 6x12 enclosed u-haul trailer to Florida from New Hampshire with my 06 Hemi. I was a little worried because it weighed just under 5k loaded and that 4 bolt hitch seemed a little hokey ? compared to the ones that attach on both frame rails.
But I should not have worried about it
The Jeep towed great! Other than a little push/pull over bumps and the gas mileage ;( would not have known it was there...
no waggling at all.
gas mileage was 13.5 or so in the beginning but the further we got the more comfortable we felt and of the course the faster we went
we where down to 12 when we got to florida cruising at 80+
Best quote of the ride from my wife.....
Me: Honey your going 80!!!
Wife: dead pan answer....Just trying to get away from the jerk in the uhual truck riding my bumper..
06 Hemi w 143k and still going strong
