I plan to begin towing a 4500 lb (dry weight) Travel Trailer with a 1998 Ford F-150 8ft bed small V8 [4.6L] 3.55 [stock] differential
Hitch is: Drawtite with torsion bars, stabilizer etc.
When I pulled this trailer home from the dealer, I noticed the truck and trailer loping on bumps. I think the hitch was adjusted about as good as it gets. It was nice and level .. good tension on torsion bars so I'm thinking my truck suspension needs some beef.
I'd like to install air bag suspension that fits above the leaf springs and only comes into play when loaded.
Near as I can tell, my model F-150 doesn't appear in many of the airbag charts I've found thru google. They run something like:
79-96 (can be fitted with the heavy duty (5000lb grade air bags) and 2004 to 2005 ditto. But my year (1998) onlys seems to take the lighter duty 3000lb models.I've written to two suppliers so far but only received mail bounces for my troubles...
Is anyone here using an 1998 F-150 with air bag suspension for towing? Or can any body advise me if there are heavy duty bags for my model? Or where to ask someone who would know for sure.
