I tow my 24 foot enclosed with a 2001 F150 Super Crew with a 5.4 and added 4.11's. It pulls fine, the problem is stopping. I do not take a whole lot to the track because of this. There is more I would like to take, but scared too. One thing for sure you are going to need is a load load leveling hitch and/or air bags. All I needed was the hitch. Here is a picture of my truck and trailer ready to go to the races. Those mirror extensions come in handy also.
I am still pulling with it, but am looking for a larger pickup. It has done a fine job for 4 years. Just drive way ahead. I have only once ended up in the middle of an intersection.
Oh yea. I get 9 to 10 miles a gallon driving from the Fort Smith, AR area to Tulsa. Sometimes a little better. I keep it to 60 mph. If I drive 70 it drinks much more gas.
