If you have a chance next time you are towing a trailer it would be great to run your rig over scales to see how the weight is distributed. Some day I may pick up a travel trailer to use as a home base and it would be great to see how that additional 10-15% tongue weight impacts payload, how much weight is pulled off the front wheels, etc.
I did weigh it when pulling the travel trailer, but it was a spur of the moment thing (stopped at a closed weight station in Oregon - they tend to leave the scales on) so the math is a little fuzzy comparing it to previous times I’ve weighed the truck.
Keeping in mind the following:
We only had 1/3rd total in our fuel tanks when I weighed with the trailer, previous weigh I am comparing to we had full tanks.
The towing setup was a 36” supertruss and a 1000lb spec WD hitch - both of these things probably added 150 lbs hanging off the back of the truck not including the trailer’s actual tongue weight.
The trailer is pretty tongue heavy in my opinion - I think Lance put the axles back a bit far, but what do I know. I weighed the tongue as 950 lbs with a hanging scale before the trailer was loaded with water or supplies.
With all those variables and keeping in mind it was a WD hitch, the trailer axles were just under 6k, the steers were 400 lbs lighter, and the drives were 1500 lbs heavier.
I haven’t weighed it without the WD bars hooked up but I have to assume they are transferring at least some weight forward.
You can draw whatever conclusions with all those variables but I wouldn’t hesitate to tow with that setup again, it was rock solid and the axle weights were all good.
