This is what I have. Jayco travel trailer dry was listed at 5500lbs loaded around 7800lbs. Listed at 30'-6" but it's actually more around 31'. I have an Equali-z-er with the 1200lbs bars and a Prodigy BC. You can see that I'm on BFG T/A KO, 35" with a ProComp 6" lift. I would say with the larger tires you'll end up in 3rd gear a lot more than if you had the stockers on. I watch the tranny gage and the minute it starts to heat up I'll drop it a gear. Once in 3rd the gage really doesn't move (the gas gage drops though). I've pulled this trailer a lot and the Titan does great. The only thing I would like to change would be the brakes, next mod I guess.
