I am at Sportsmobile west today. I asked about how they stiffen the body after cutting the top off. He showed me the huge frame that makes up the pop top. He said it is robust to pass a vertical load crush test. That thing is crazy stout and CRAZY heavy steel and must way at least 200 lbs and maybe 250. I would expect that the issue may be handling ( or lack thereof) having 250 lbs wrapped around the top of an already tall roof with a tendency to be top heavy in its stock form. Wow.
Ken,
I have about that much weight on top of my roof (UJOR 6" lift, 35" tires) currently with my FrontRunner rack, Autohome Columbus RTT/etc (no water or fuel), and no handling issues knock on wood. In fact it feels more stable than my G500 did with the same stuff up top on it.
Aluminum up there would be better IMHO.
