Rad setup. I have the same problem with my 15' f150 (pictured above). I have a similar hitch rack for my 500 exc that I put on. With the RTT/Rack/Tonneau the 500 exc hanging off the back, and a 70lbs worth of mountain bikes for my wife and I, things get pretty loaded down. Definitely one of the few times that I wish I had gotten a 3/4 ton truck. I'm actually going to either add air bags or an add a leaf soon to deal with the load. Definitely pushing past the comfort zone on a half ton.When you max out your Gladiator capacity.......our new build is coming along. 2017 F250 Platinum, 4 link BDS lift, 37s, racked out.
