If you travel in or through Oregon, be aware the State scales are always operational even when the office is closed. So when you see a closed one, you can do an exhaustive weigh job. There is only one scale which means you have to weigh the front, rear, and trailer wheels separately. But a little simple math will give you totals. Before you unhitch and weigh empty, take the opportunity to do something you can't do at the truck scales.

Back the rig up and now weigh only one side of the front, rear, and trailer tires. If you are really good you can measure each wheel of a two axle trailer individually. Now that you know the weight of each wheel on one side, you can calculate the weight on the other wheel.

Lastly weigh the truck without the RV to determine the pin weight.
