I can re-inforce the mount as needed.
The real questions is do you like 400/100 valving?
How much weight are you caring?
Last trip I had 850lbs in the back(three kids and all the stuff). Total weight close to 6300lbs. I am running Rovertym springs(R4 and R1).
When I am fully loaded I am that heavy for sure.
I have a full rack with a full roof top tent. I have a pelican with a couple hundred pounds of tools and parts, a fridge feezer. lots of cast iron cooking equipment. fuel , water the whole shabang.
The 400/100 is plenty of dampening and it really control body roll as I am running without either sway bar. I am running the 5" rovertym springs front and rear so I do have some good spring rates in there.
The jounce shocks are what really completes the set up. I cant believe more people havent flocked to them yet. They eliminate those hard bottoms that damage trucks and make the driver cringe. The best part of them is the amount of control they give you. What they do is soak up that huge amount of force that toss' the truck. What I have found is they allow the shocks to work better. To eliminate that motion with just shocks you would have to suffer from the hard ride of a overly dampened shock set up all the time just to have the protection those few really rough spots will need. The jounce shocks are progresive so most times you will not even feel them. as you start cycling them hard all you feel is a gentle click when they make contact but the progresive nature makes the soak up the force and bring you to a soft bottom that wont launch you like a poly bump stop.
