Towing capicity 2008 F150 HD

I think the large tires/wheels are taking away from your 3.73 gearing. This is likely the reason for the low 11K GCWR. It may still work for you, since it appears you live in flat terrain. If you plan to tow out west, in big hills/mountains, it will be a struggle. It also depends on the number of passengers, how heavy you load truck and trailer, lots of variables.

5.4 , with 3.73 gears and it does have a hitch and trailer light connection on rear

Here is a link I found with information on the truck, mine is a 4x4. My concern was the GCWR of 11,000.

Welcome to the forum! It would help to give a little more info. Does your truck have the 5.4 engine, 3.73 gearing, tow package, with larger radiator, and transmission cooler. This all makes a difference in rated tow capacity. I think your truck would likely work, for the trailer mentioned, if it has the tow package.

You don't list enough details on the truck so it is hard to say

I had a 2009 5.4 v*, 6 speed trans, 3:31(I think) rear end and the towing package. It did very well with a trailer that size. also I believe 2009 was the 1st year fir that generation so 2008-2009 could be a big change
