2017 Palomino Backpack

I do like it so far, going out this weekend for the first time in it. I was also looking at the 1251 but did not want it to extend past my 8' bed. the one I got was the SS-1200. Already had helper springs and air bags on my truck, the helper springs kept it level, did not even inflate the bags beyond 15 lbs. I called the dealer wanting to ask about the other charge ports on the outside and also the low point tank drain does not seem to drain anything. They never called me back. Looks like I can remove a drawer inside and probably see where the wires go, my guess it that they are not connected to anything.
