Keith J, you were too kind with your math.

At a 3000# pin weight (21% of 5ver GVWR), the truck will be 1300# over its GVWR and exceeding the tire & rim ratings!

THAT IS EXCESSIVE.

While I agree their weights are excessive your comment puzzles me. According to the Crossroads site the max pin for the
26RK (trailer in their sig) is 22% of 11625# or 2557#. That is approx 600# more than the available capacity. Where did you get 1300# from?

OK, on edit - you are referring to their proposed NEW trailer, I was looking at the numbers for the one in their sig. They are already overloaded and plan to make it worse!

My aluminum wheels are rated for 4,142 each.

Some times you have to use common sense in what one does.

I have a Classic 2007 2500HD D/A LBZ CC SB 4X4.

I am wanting to purchase a 5th wheel with a dry weight of 10,530 w/14,200 gvwr. The pin is 2,230 lbs dry.

Thanks.


Keith J—here is my math.

Recent posting.
Truck front: 4200#
Truck rear: 3060#
GVW: 7260#

Add DW, dog & 100# with my estimated front/rear distribution.
Truck front: 4300#
Truck rear: 3200#
GVW: 7500#

New 5th wheel:
dry weight: 10,530#,
GVWR: 14,200#
Dry pin wgt: 2,230# (21.2% of dry weight)

The estimated GVW pin weight would be 3000# at the same 21.2%

Therefore, the combined TV & 5ver weights would be about:

Truck front: 4300#
Truck rear: 6200#
GVW: 10500#
GVWR: 9200#

Therefore the truck is over the GVWR by 1300#.

The truck & 5ver together will just squeak by the CGVWR OF 22,000# by just 300# if the 5ver is at its GVWR.

OK, they are not the pre-2008 2500HD OEM ones then, which I believe are rated for 3200# each. Which is why they were not even an option on the 1-ton Classics.
My earlier comments did not comprehend the trailer you plan to buy, only the one in your current sig. You are already mildly overloaded but you are consciously moving forward to significantly overload your truck. And I'm afraid overloading the truck by up to 1300# does not fit my definition of "Common Sense".
You obviously intend to do it anyway regardless of those on here who say "don't". You choose to take the advice of the one or two who don't believe in weight ratings instead. You will have a load that would be 900# too much for a 1-ton SRW. (3500 SRW only buys you 400# more payload due the weight of the extra length).
This is my last post on this topic. Not going to bang my head against this wall any longer!!
Just drive safe!

Thanks all for the help.

If I add an air lift, I will be
good to go for about 3,000lb pin. I may even add higher rated tires
just for extra safety sake.
Any comments?
Thanks a lot for the help.


As I stated earlier, and as many others have stated: "...THE GVWR IS THE GVWR....IS THE GVWR....IS THE GVWR....IS THE GVWR....".
Adding/changing/upgrading tires - shocks - springs - air bags - etc., is what some folks consider to be a "cure-all". None of these, however, will EVER change the designated GVWR of any vehicle.
I myself would dread the possible ramifications of an accident, (or?), while exceeding mandated weight limits. Insurance would say "bye-bye...you're on your own", law suit potential(s) would be ripe for the picking, etc.
Simply my $.02 again.


Enjoy the journey.....

The subject truck is "Classic 2007 2500HD D/A LBZ CC SB 4X4" per the original post.
If the aluminum wheels are OEM, they should be rated as Keith J states, 3200# each.

Where did the 4142# each rating come from??

I agree with Keith J.
I'm through posting also.
If you do this, drive it carefully, VERY CAREFULLY!

Problem is HUTCH, (other than perhaps the province of British Columbia in Canada) there appears to be nowhere with any legal repercussions for exceeding that rating.
We tried using facts, they have been ignored! Don't waste your time!
