New 2018

Truck is bought and I will be trading my 2014 for it next week ...in the meantime the dealership is doing some tweaks to y 18 including putting perch collars on
front measurements from floor to bottom of wheel well is 40.25. rear measurement is 43.25 ...about a 3 inch difference...2.25 RPG collar is going on ...did anyone else have a measurement difference that large ?

I went on a few spirited runs on the control roads and the rear settled down to almost level.
However when I installed the deaver springs I noticed the the springs were sacked already (reverse arched). That was at 4000 miles whiched seems pretty early but I drive the shit out of this thing and have dirt roads all over over mountain which call my name.
