That is a really beautiful 60! I have a little suggestion, which you may choose to use or not. If I read correctly you have a BDS lift right? I would take out the rear overload and put the stock one in if you have it. I've got the same springs (Ironman version but same thing pretty much) and that overload has been bugging the crap out of me. I have ran around with pretty much 300-500 lbs worth of tools, stereo, snowboarding equipment, and other random stuff all winter long and it rides pretty smooth aside from the stuff in the back flying all over the place (another suggestion, tie downs of some sort lol). I completely emptied my truck the other day, and it lifted the rear of the truck about 2 inches taller but it's very bouncy and the shackles are pretty much vertical again. The overload seems to be almost twice as thick as the stock one and it curves with the arch of the springs rather than being flat. It limits flex like crazy, makes for a bouncy ride, and hasn't seemed to allow my springs to break in at all because the minute they other leaves contact the overload, they pretty much quit flexing. I was even considering finding a way to put my Ironman overload in upside down for more travel, and carrying capacity. Im no pro though, and have no clue what you plan on carrying either. Sliding rear windows would be great too if you plan on sleeping inside it!
