Anyone have any advice on potential upgrades to help the back-end of our trucks from sagging when pulling loads? I have a 30 ft, 7k lb travel trailer I pull with my '17 Raptor. Engine and transmission pulls it like a beast. However, even with weight distribution bars the trailer still places noticeable sag on the rear shocks. I realize this is not the ideal truck for pulling my travel trailer but I have been spoiled by the Raptor's capabilities elsewhere and would be disheartened to trade my truck for this one condition. Most of my trips are 1-2 hrs one-way, but some trips are recently turning into 6-7 hr one-way. I'm sure this is not good for the shocks long-term. Should I be concerned about this back-end sag for these quick trips or should I consider air bags, Timbren SES (suspension enhancement system), or doing nothing?
