have both sides done now and had to notch out the crossmember. i used a piece of 2x3. i will have to notch a little out of the crossmember that is attached under the bed. no big deal though because that crossmember is around 4 inches tall. next up is to figure out shock mounting and putting in a 2 x 4 cross brace and bag mounts...i would like to also do the hidden hitch so when i get the sport bumper i can flip my tag down and hook up. i only need to use a trailer every couple of years or so...may or may not do that since its not really a priority
