Just because it is zero degrees outside and I don't feel like freezing yet, I built a 2020 half ton Trail Boss crew cab with 6.5 box LT with a 6.2L. The tow capacity says up to 13,400 and a bed capacity of 2,250. I am sure this is with an double cab version not a crew cab, but it wouldnt be too far off. The build price was 53K comfortably loaded with tow package and all the tow cameras available. I don't think you need a 2500 HD to pull 8K unless you want to and you clearly don't. The 6.2 is a heck of motor and with that 10 speed it makes it that much better.
