Do rv's with cargo trailers have to stop at Ag. stations?

California requires RV's to stop at the AG Stations? I thought only commercial vehicles had to stop? No state requires non commercial vehicles to stop at a weight station but the AG stations I have seen have always been a separate facility from the weigh stations.

If the vehicle you are driving does not require USDOT numbers you do not need to stop at any weigh stations. I do know Florida does not require RV's to stop at the AG stations. Or at least I had never been pulled over when I drove by it in Florida.
