I use my truck for exactly what you want yours for. I am out hunting/shooting in the backcountry almost every weekend in SoCal. Lately I have taken my truck places that I never thought I would be and it drives way better than I thought imaginable from a truck this size. I am running 35" Hankook Dynapro MT's cause I need an "E" rated tire for my 17" wheels cause I tow a heavy 5th wheel. I had BFG AT's which I have nothing bad to say about but no "E" rating for my tire size. I have been messing with my suspension a lot lately too. Started with an Icon 4.5" coil lift and blocks in the rear. Suspension was alright but not good enough. I have been dealing with Carli Suspension lately. Carli Suspension - Ford Super Duty Suspension Systems and Components
I am one of the first to put there King Coilovers on about three years ago. Recently I replaced my stock 05 rear leaf springs with 08 stock springs. Ride was better but decided to add the Carli 6-leaf mini pack in the rear with Carli spec rear Kings. Made an enormous improvement for the rear of the truck.
The owner of Carli Suspension bought a 2011 Superduty so he could develop a better suspension for the Supeduties. His valving is spot on for the 2011's and has some valving for the 6.4 motors. He is still trying to perfect the valving on his shocks for the 6.0 motor. I have kinda been his ginnie pig because I am close to there shop. He revalved my front coilovers to his new spec and told me to try it and give him my feedback. The new valving on the hwy is amazing but I had some concerns about it offroad and tried to explain to him. Now he wants to go with me the next time I am out in the dirt to see what I am talking about so he could correct it. If that isn't excellent customer service then I dont know what is. He wants real world feedback from me cause I use my truck how most real word people would.
You do not have to get the coilover to get the same ride quality. His truck is still coil springs and pin-top shocks. He just valved the coilovers to ride the same. If I were to do it again I would have stayed with coils and shocks cause it is cheaper. Also I do not have the optional secondary bypass shock on mine. Carli told me that I do not need it for what I use my truck for. That is pretty stand up of a company if you ask me. He could have easily made over $1k off of me if he tried to sell me the bypasses. Though they look way cool.
Truck just got detailed. It is usually very dirty. I need to take some pictures of it while it is being used in the dirt. I would atleast give them a call and tell them what you want. You are close enough that you could take his truck for a drive. Hell you are close enough to me too. You wont be disappointed.
Where you hunting this winter?
