Just drive on and hit the intercom button. Tell them that you're an
RV. They'll tell you when the weighing is done and where to come to
get the ticket.

Truckers (and you) are interested in axle loading. Truck axle weight
is regulated. You care because of tire loading. When I weighed my
MH, I positioned it so that the front axle was on one plate and the
rear on another. For a trailer or 5th, I'd want the trailer on one
plate, the rear tow axle on another and the front tow on yet another

Very unlikely. If you look at multi-axle setups, you'll see that the
springs are hung such that the load redistributes itself under normal
>4) All the scales seem to measure both tires of an axle at the same time.

Right, if you load the trailer wrong then the weight will be
imbalanced side to side. Unless the problem is gross (trailer tilting
to one side) it isn't a problem per se. Overloading the tires on the
heavy side is the main concern.
