I towed a 25' Hallmark enclosed trailer last night about 100 miles. It was extreamly windy and the trailer was causing the truck to sway really bad. I ordered air bags for it today and will install on wednesday. I will then be towing 800 miles round trip. Truck has plenty of power. Miles per gallon 8.3 @ 73mph
if you use the truck for offraoding I would not recommend airbags. I put many, many sets of both Firestone Ride Rites and Air Lifts. For on the road they are great, but I had many that were used on ranch trucks that ended up getting busted. Even though these trucks weren't "actively" offroading, just going normal speed on rough ranch roads threw the geometry of the system off and ended up puncturing bags. We replaced several under warranty, but it finally became such a headache, that the manufacturers stopped warrantying them. If you don't offroad, then by alll means they are great. I have a Roadmaster Active Suspension system, just put it on Friday, and need to dial it in. They are heavy duty, adjustable, and the same price as bags (unless you get the built in compressor on the airbags which is nearly double). I had these on a previous F-150 and swear by them. I also sold many of these back in the day, and never had an issue. They help with wheel hop and axle wrap, and I am thinking when I get it dialed in correctly, that it will lessen the likelyhood of frame damage from bottoming out. The application for Raptors is not listed so you can't order thru a regular retailer very easily, but you can call them and order it direct.
**edit** they are adjustable, although you do have to get under the truck and wrench on it a bit
