2014 F-150 4X4 towing 2018 Winnebago 2250DS. Had about 6-7" squat using an Anderson rig. Installed a RAS 3611YHD this weekend. The result on the test haul was good. Front fender to ground is 38", rear fender to ground is 38". Truck and trailer are straight and level now. Dry tongue weight is 550 and added 180 or so pounds for dual propane and front compartment loading. Utilized the #2 slots on the front of the RAS system and the larger gauging disc that was provided. All worked out well the first time. Truck rides great without trailer as well.
