I asked on another thread about truck mpg and said I was planning on renting until my ordered truck came in. But I couldn't resist the price on a used 21 F250 with 12000 miles on it. It is a STX, so pretty basic, but better than renting. I set up the hitch and had the front end measuring just over a 1/4" difference between no trailer and having the WDH on. I didn't have time to scale it on way to the destination. It seemed a little light in the front end. So on the return trip I stopped at the scales.

I went to the scales prior to leaving the campsite with the trailer, Truck unloaded was: 4080 in the front and 2840 on the rear. Gross weight was 6940 (for some reason it was showing 20 pounds for a trailer)
Truck and trailer with the original hitch setup was: 3860 front, 4280 rear, and trailer was 6120. Gross weight was 14260.
Truck and trailer after adjusting the hitch: 4160 front, 3880 rear, and trailer was 6200. Gross weight was 14240.

My sticker on the truck shows front axle GAWR of 4400 and rear GAWR of 6340

It drove a lot better after adjusting the hitch. I was able to drive with one hand after fixing it. It also took out a lot of sway, as the winds were pushing me around all the way to the scale. I also was figuring that my camper was closer to the 8500 lbs, but that is the GVWR for it. I am figuring that the camper is right around 7300 loaded (just subtracting the gross weights from each other). I forgot to get a weight without the weight distribution.

So all in all, driving back home was a more pleasurable drive. We have another trip planned this week, and it will be a lot longer drive.

BTW, the truck is a CCSB 4x4, 6.2 with the 3.73 gears. I'm hoping to get a VIN soon on my Godzilla truck. I was getting 7.8 mpg according to the trip computer with this one traveling 65 to 70 mph. I haven't made it to the gas pump to hand calculate it yet.

Forgot to add: the camper is a 34' Jayco bunkhouse

 

With the WDH configured, you've added 80 lbs to the front axle. That may have come off of the rear axle. In the grand scheme of things, 80 lbs may be within the margin of error and isn't enough to worry about.

As an aside, it's possible to shift too much weight from the rear axle to the front, thus making the rear axle too light. If you're in low traction conditions that could be bad and cause the rig to jackknife.

 

Cat scales are supposed to be certified within 20lb. So that explains some of the variations you are seeing.

With the final adjustment it looks like you are at 7,300 lbs with 1,100 tongue weight.

before the final adjustment it was 7,320 with 1,200 lbs tonight weight.


id say you are set up well. The fact that it drives better confirms what the numbers say.
