So after years of changes and trailers, I have a new truck that has a 2.5 receiver, I have to use the sleeve that comes with it so I can use my other parts to tow. So I want to go to a solution that will let me tow everything with just one drop hitch, trailer I have goes up to 12k loaded. I want to be able to tow the limit of my truck (sorry 3500hd- 20k limit). What type and brand of drop hitch are you using and why???
