I like how you used the roll bar mounts in the tub for your tent rack. I would of done it that way, but I wanted to keep my tonneau cover on, so I made my rack external mounted.
I was looking at getting a custom tonneau cover made to fit around the bars but a stock tj cover fits perfectly from bar to bar and leaves a 6" gap at the back for my water tank to stick up out of.
What tire pressure is best for a trailer? I just recently bent my 2k lbs rockwell trailer axel and the guy I buy them from suggested that my tires might be to hard for the weight of my trailer (800#). I ended up with a 3500# rockwell axle to replace it and hopefully eliminate that problem.
