Big truck woes

Thank you all, you have given me plenty to check and research. Just to clear up a few things, it is only the copilot and I, unless you count 4 pawed children (no sand boxes and tree houses). I did run by and check the trailer, and it is 8,679# dry and max 1,296# cargo, so 9,975# max loaded. Little more than I remembered. The Reese hitch that we have does have the friction anti-sway pads in the trailer bracket and the truck does have the anti-sway electronics, though for the record, it does more to scare you into stopping vs doing anything useful. Based on many of the comments here, I am leaning toward working on the DW to convince her that I need a new truck :). I think we would be more comfortable improving the situation with a heavier vehicle rather than patching it and still being underweight.

Thanks again
Ken
