Good read. Thanks for sharing. Couple of observations. 1. You mentioned sway control chains. I'm thinking you may be referring to the weight distribution hitch WDH (bars), which have chains on the ends that hook to the trailer. If so, do you also have the anti-sway bar beside the hitch ball? Or, does your WDH have built in anti sway features?
2. Another benefit from half ton to 3/4 ton is the tires. Half ton probably had passenger tires (load range c) which have soft sidewalls allowing more sag and sway. The 3/4 ton probably has Lt tires load range E with stiffer sidewalls, for load bearing.
Either way, you've got a good set up now a great story for the campfire. Or forum. Lol
