Cargo carrying capacity

When passing through Oregon a few years ago I stopped at one of the state run digital scales. That Oregon Weight Station was closed for the night, but Oregon at that time left its scales turned on 24/7 (I don't know if they still do that - maybe someone can report). I was able to weigh just the front axle of my Roadtrek without even getting out of my RT. Nice big digital numbers displayed to the left of my driver side window reading 3,900 lbs. Pulling forward, 4,950 lbs for just the rear axle. Backing up and putting both axles on the scale 8,800 lbs. Putting just the front and rear rightside tires on the scale I got a reading of 4,300 lbs. My 2002 Chevy 190P RT has a GVWR of 9,500 lbs and was 7,370 lbs when it left the factory. At that time I used the scale I was traveling with full tanks and cargo for two full weeks. I recommend that everyone have their unit weighed. While I was 700 lbs under my GVWR at that time, I know a number of individuals that are overloaded and don't even know it.
