I have been blasting past state line weigh stations under the impression that they were for commercial vehicles only. During our recent trip I noticed a lane for RVs at one state, maybe Nebraska. I did an internet search and found this:
Weigh Stations | AAA/CAA Digest of Motor Laws
Some states say commercial but some require weighing based on GVW, so,e are 10,000, some are 26,000. Here is an extract of what I think are states we should stop at, some call for "trucks" to stop, one could probably argue that we are not "trucks."
