X3 I agree with this. Choose the truck that best fills your needs.
The 3500 SWR does it for me.


What is the GAWR of the axles on your SRW truck?
What is the GVWR of your truck?
What is the actual weight of the truck ready to tow? Per axle?

Thanks Jim

Hi Jim,

Answers to your questions.

1. The GAWR of the axles of my 2012 3500 Extended Cab SRW Truck are:
Front - 6000#(I have the plow package thereby higher rating for front)
Rear - 7050 # (Limited because of tires)
2. The GVWR of the truck is 11,600 pounds
3. Actual weight of truck loaded with two Honda 2000 generators, 6 gallons of regular fuel, two passengers, one dog and a full tank of diesel and diesel exhaust fluid is :
Drive axle - 3460#
Steer axle - 4760#
Gross weight - 8220#

Weights of my rig 2014 3725 and truck on scale. (Trailer loaded plus full tank of water which I usually don't do.)

Steer Axle - 4800#
Drive Axle - 6620#
Trailer Axles - 11260#
Gross weight - 22680#

My Math:

1820# under GCWR (truck GCWR is 24500#)
180# under GVWR (truck GVWR is 11,600#)
430# under rear axle rating (truck GAWR is 7050#)
1200# under front axle rating (truck GAWR is 6000#)
3200# pin (hitch) weight (22.13%)
14460# gross weight of Montana (Montana GVWR is 16000#)
1540# under Montana's GVWR
Maximum Trailer weight for Truck is 16,900#
2440# (under maximum trailer weight for truck)
GAWR for Montana is 6750# per axle. I have the Marabomb ST235/80R16E rated at 3420#( will be changed out)
More math,(making assumption the weight is equal on all tires, which I know isn't the case.)
2815# per tire (605# under tire rating of 3420#)

The only thing that has changed since I weighed in September is the BD3 air hitch. I believe it is a bit more weight, but I will find out when I reweigh both in April on trip down south.

This is a bit more information that you requested Jim, but I think if folks weigh their rigs and know their weights they can make better choices of the type of vehicle the meets their needs. As you can see, I am close to my maximum both with the GVWR and Rear Axle Rating (limited because of tires to 7050), but still within the ratings. This truck meets my needs perfectly. Some people will want more margin, and I am fine with that. Again it is their choice. I may be a little silly about weighing my unit yearly, but I have found that the rig will slowly puts on weight just like me if I do not keep it checked. My DW is a great cook and our 3725 has a lot of space to put things. My past SOB was also kept in check by yearly weigh ins because my past tow vehicle was a 1999 Dodge with the Cummins and a GVWR of only 8800 pounds. It didn't take much to be over. I was lucky that the pin weight didn't exceed my ratings, but again I had to keep things in check. Towing ability was never a issue, more than enough power.

I hope this helps,

Jay
