Hi, I've got a 99 Expedition with the rear air suspension that seems to be riding rather low lately while towing. Just wondering in anybody else out there has any similar experience with this and what you think about switching the rears to regular struts/springs. The truck seems fine on regular driving, but loaded down with gear and the car on the trailer the rear really sags (didn't use to or not as much at least). It doesn't seem to affect the truck, just looks bad and seems like a bad idea.
When I search online, all I keep getting is links to a place called strutmasters that sells a conversion kit. There doesn't seem to be any mention of tow ratings on these, though. Anybody do this or use another brand?
