To help handle the AF811 I did the following; (with 2011 F350 diesel, SRW
- Helwig Bigwig rear sway bar
- front springs from an F550
-Rancho 9000 adjustable shocks
-upper and lower Torklift stableloads
-19.5 Vision wheels with commercial Michlens. Load range H, 16 ply, 120 PSI. Drive treads on the rear, but steer treads on the front (quieter) Supposed to be good for 100k.
Still just didn't feel safe at times, especially on tight to moderate highway curves. Finally went with Firestone airbags as the last thing. I wish it had of been the first thing I did. Slideout (dinette & 8cu/ft fridge) are on pass. side so 55 psi over there. Then 50 PSI on driver side. SO MUCH BETTER.
We have taken it to Yellowstone, then Vancouver Island and back through Canada. One month in Nfld. Two trips to Sarasota, Florida. All good now. Lessons learned. Take care. Be safe.
