    I suspect it is the difference in distance from the rear axle to the hitch between the SB and the LB. For the LB, the distance is probably farther causing there to be more weight on the rear axle and more unloading of the front axle (that is why most of us like to use WDH). Plus with the Cummins SB, you already have more weight on the front axle.

    Are the 6.4L tires 10 ply inflated to 80 psi?

    Also, how much weight is in the bed?

    I think the CCSB and RCLB are the same overall length. Even if they weren’t the axle to hitch distance is identical on all the trucks, because the extra length is between the axles.

    Sometimes. We've tried changing pressure.

    But again, I'm running the same tires on the '14.

    Could be, we added rear air bags to see if that would help because some have done so and said it did. Not with ours.

    Roger that. I still suspect that the issue is unloading of the front axle. The Cummins truck will have more weight on the front axle.

    Also @JD Mark, air bags will just level the truck, they do not move weight to the front axle, the weights on the axles will remain essentially the same.

    Yes and no...if it carries the load higher\better, it won't be dragging butt. A little.

    I suppose we could throw the plow on it and give it a try. Although, it happens with a loaded or unloaded trailer. If it's unloading the front axle with just some tongue weight, an engineer or 3 needs to be fired.

    You hit the nail on the head! Too many macho guys running around thinking that coils are only made for cars & light duty trucks. Comical this coming from a Ford guy! :laughing1:They are currently the worst for having the squats with a load on. Just keep an eye out while you are out driving. You will see what I mean. I am not a Ford hater... in fact I think all the big 3 have some really nice trucks out right now. I have been pulling all kinds of different trailers with my 16 Ram 2500 w/6.4 with none of the problems the OP is inquiring about. My latest is a 38' 5th wheel that weighs in at 13,200 loaded. Besides being a little light in the gears it pulls very good. With the trailer hooked up it drops the rear about 2". So basically levels it. OP... you were talking about a diesel 2500. That will pull a 10k trailer around with ease. Don't think you could go wrong with a Chevy 2500 with the Duramax either. Wooops... did that come out of my Mopar loving mouth?!? :shakehead:

    The problem with a 2500 diesel is the payload. You will be around 2100lbs or so for payload depending on the package and options. A 12000lb camper will have about 1000-1500lb tongue weight which won't leave you with much room. If you want to pull a 5th wheel with a 2500 diesel you will likely be over payload.
