Presently with a Ram 1500, 5.7 Hemi. It tows OK, but i feel a bigger truck would do the job better. Living in the UK, there are far fewer trucks of that ilk, than over there. So, it's not an easy job to find the right one.
I had the truck before the trailer, and it had a hitch and air suspension already fitted. There is more than enough power, but having read some of the threads regarding tow vehicles, I feel a larger truck would be more suited.
It sits nice with the air sus, and it rides beautifully, no problems.
