i was looking at 2019 GM 4500, 5500 series
and wow they derared the trucks instead of going up like everything else. my 08 has a 11k rear axle and 7k frint. 17k gvw in a 4500. looks like the upfitter derated mine a littte when put the utility bed on it. You cant get but a 16k now. Not even ordering. Derating to lees in 2019 i know a new truck aint for me.
