It's the roof itself that's the limiting factor, along with the weak bolts up front. The trailrax roof rack only increase load capacity IF you get the side pack rax with it. They bolt to the roof rack and the body of the bronco under the top. If you have a rack that only connects to the top...
Ground tents are quite lovely. I only got a RTT because I do camping so often with the youth groups that my back is dead. I need that comfort! That being said, an offroad trailer with a nice RTT is pretty dope.
I have the trailrax, they have foam inserts all around the brackets that connect up top for the clamping portion to eliminate that issue completely. If you want pix, I'll take some. I also added rubber strips to the parts of the tent that touch the rack so there is no metal on metal contact...

Same boat....I planned on ditching the shitty stock tires and that was about it. I'm on my 2nd lift (upgrade) and about 10-15k in total parts/accessories now if you include labor.
