I have a 2008 F150 King Ranch Super Crew 4X4, with the 5.4 and a 6' bed. For the past two camping seasons, I've been towing a 28' tag-along that has a GVWR of 7200lbs, and the truck handles it great. Were are looking at a 30' tag-along that has a GVWR of 7623. In your professional opinion, or experience, will the additional weight become an issue? The axle code on my truck is B6. Your "professional" input would greatly appreciated.
