The Benefits of Weighing Your Tow Rig Twice
So often, RVers will pull up to a scale and get the weight of the tow vehicle's front and rear axles, and the trailer axles. They drive away, and later sit down with their calculator to come up with f...

So was that the readout for your truck and trailer?
That would put the pin weight around 3,200 pounds on your trailer. Is that including your smart car in the back, or without it? It seems like with the smart car, the pin weight would go down by say 200 to 300 pounds or so.
Also interesting is that the front axle weight is about 150 pounds higher with the trailer attached. It seems like with the hitch pin centered over the axle and 1" to 2" forward, only a small portion of the trailer pin weight would transfer to the truck front axle. In this case the truck GVW went from 7700 to 10,900 pounds or up by 3,200 pounds. 5% (would be 160 pounds) is transferred to the front axle.
All of this is very interesting.

Excellent observations, Fred. It’s certainly observations one would not see with just only one weigh-in.
No, the example above is not my rig. (I added a note above to that fact.) But you do point out correctly that pin weight is usually reduced when heavy items are garaged in toy haulers. In my toy hauler, the pin weight is reduced by 325 pounds. (From 3,725 to 3,400)
The reason that there appears to be a sight weight error for the weight shift is likely in the scales. Most scales for heavy weighing only have divisions of 20 or 50 pounds. Therefore, the potential for error is 10 pounds for 20 pound division and 25 pounds for 50 pound division.
