I am like Havasu Bill, with a 2500 and a Cardinal 3250, I have no problems truck goes like it is supposed to.
Here are my weights and photos, In my opinion I am on the edge and I have no problems with that I have 410s and that increases my Gross combined weight rating.
Tires are rated at 3195 ea. x2= 6390 lbs.
My 5er has a lot of added weight, this is the max I would ever have. just came back from a 2 week trip.
DW, just filled up fuel plus 16 gallon extra fuel take "full", cross bed tool box with approx.125 lbs. of stuff not counting the box. (the box is no longer in, didn't like the thought of hitting 5er).
with no air in air bags for some reason. with a Curt 20K hitch.
So here it is.
looks like under on front GAWR. by 480 lbs.
Over on rear by 370 lbs. now that the tool box is gone thats better.
Under on 5er by 1,190 lbs.
Over on total 660 lbs.
With that all said, I am in the process of trying to figure out how to swing a 1 ton.
