I use a Torklift 48" extension with a Husky WD hitch with 1200 pound bars. I tow a 7000 pound horse trailer. tongue weight is 1100 pounds. I have been trailering that set up for 11 years now, all over the US, over the Sierras and Rockies in all sorts of weather. The trailer tracks perfectly with this set up.
