Hello. New to forum and am looking to buy the Flagstaff sister model to the 2706. Been over researching our decision for a while. Love what you’ve done to your rig. We will be towing with a 2017 Expedition EL as well. Have you had any issues with tongue weight or towing characteristics? We currently tow a 27ft Kodiak that is about 1,500 lbs lighter and the truck performs very well. Added Sumo Springs in the rear to take some of the squat out. Thanks for any feedback.
