Can you get the Max Trailer Tow with the Tremor? I played with the build and price and didn't see it? Hardware-wise I think it changes from the semi-float to the 3/4 float rear, and that comes with a miniscule increase in brake size (just enough to confuse the parts guy a few years from now)...
For me, the appeal of the Tremor is that you get the off-road upgrades while still retaining the ability to use it as a truck, i.e. payload and towing (tongue weight). Springs compress when you load them. There's no way its gonna sit level empty, and stay level with 1,500 lbs in the bed. So...
