Your truck will pull this load just fine. I will just say take your time, watch your pinch points,turns and dips. It would be a good idea to take your truck to a large parking lot and make some tight turns just to see how much clearance you have. The only thing I can see by your pictures is, your tool box might be pretty close. I don't think I could have a box in my short bed GMC. Just an observation. Take your time and you will be just fine.
