What is the curb weight? I’m not in the least bothered by the length or GVWR on the trailer. My 2013 handles one in similar size and weight just fine. You just have to slow down sometimes if you want to keep some gas in the tank. But control has never been an issue. I do wonder about the really low tongue weight for a 10k gvwr. The old rule of thumb is 10% on a bumper, +/- 15% for 5’ers. The less tongue weight the less control especially once the trailer exceeds the weight of the truck. I towed a small jay feather with too much tension on the WD hitch and it was a kite.2018 F150 3.5L 4X2 145"WB 5'5" bed 3.55 Axle Ratio Max Tow Package GVWR 6750 lbs.,GCWR is 15800 lbs., Payload 1786 lbs., and max loaded trailer weight is 10,700 lbs. Used my haul gauge on current rig and have 800 lbs tongue weight and 700 lbs. with WD hitch. Have been towing 30' TT with GVWR of 7495 lbs. with no issue. I did install a Roadmaster active suspension for increased stability. Would like to consider a 33' with GVWR of 10400 lbs. and dry tongue weight of 660. Concern is mostly length but obviously tongue weight as well. Don't anticipate much boondocking so don't think I would ever travel with full tanks and lots of gear so not sure if I would ever come close to new GVWR. Anyone consider making a similar move or has done it already that can offer advice?
