These threads relating to suspensions, brakes and tires are all to common. We are making a long term investment and plan to put some serious miles on our new 3585RL. We're biting the bulllet now instead of later and decided to have MorRyde put their 8K IS and disc brakes on before we ever hook up to the truck. They will also match to the hitch height of the truck for a level, balanced setup, and mount the G rated wheels and G-614's I get from the factory. Thanks to all of you for helping us figure this all out before buying off a lot and learning the hard way. No prevous damage from our Alaska, the Rockies or the Desert SW ventures and we want to keep it that way.
