Tell you what you need to do is learn some reading comprehension. The post was not about 150 capabilities but about how shocked I was with a 1450# payload on a 2500 Cummins. Previously had a GMC 2500 that rusted out underneath. Got the 150 because DW had 2 spinal surgeries and was in line for a third and the ride was much better than a 250 and she was more comfortable driving it and accessing it. It does the job with our 7700# TT within all ratings and while I would have gotten at least a Heavy Duty it did not fit our current situation.
