Agree. As a retired trucker I can attest to getting a bit 'upset' at RV'ers taking what I thought was too much time fooling around on the scale while I needed to weight before I could even start my trip.
Point well taken. Those folks get paid for driving, not waiting; and I had also suggested in my earlier post to get weighed and move to a spot away from the trucks.
Everything we buy it handled by a trucker at some point.
The call button and intercom is usually higher than I can reach from an Expy seat, so I send the wife in with her cell phone before I pull onto the scales and we communicate with the scale operator that way and that makes it easy to pull on, get confirmation and pull off and get out of the way. I've gone mid-afternoon when the scales aren't busy. Only if no one is in line when you get your rig weight, disconnect the spring bars and get a 2nd weight while on the scales before going back around with the solo Expy. Subtracting the solo weight from the F/R axle weights with the spring bars disconnected should give you the tongue weight. The TW plus the trailer axle reading without the spring bars will be your GVW for the trailer. Then you can determine if your TW is 10-15% of your trailer GVW. If not, you will need to figure out how to move the heavier stuff you store in your trailer fore or aft accordingly. Your spouse in the scale office won't significantly alter your scale weights. But it would be good if you moved to the driver's position (stand by the driver's door) when getting the unsprung weight so that your position doesn't color the tongue weight calculations. These scales typically have a 20 lb resolution. That is, the scale readings increment in 20s. Assuming you weigh 200, it makes a difference on which scale section you're standing on.
Once you get all this dialed in, if you still experience a lot of bounce other than concrete highways, shocks may be the next thing to look at.
