When the truck stop parking lots and interstate rest areas are signed "Commercial Vehicles Only", I will quit using them.
IMO, the trucking industry needs to start lobbying the government to see to it that there are enough places for truckers to stop so that they can comply with the government regulations.
There was an article on the local PBS station the other day about this issue, especially as it applies to female truck drivers (too many places where truckers stop are crime and drug ridden, the females don't feel comfortable).
I can understand your concerns, but 99% of the people on the highways know nothing about the problems. You can bet that if the two RVs hadn't been parked there, there would have been two or three more trucks, and you still would not have had a place to park!
The trucking industry is going to have to step up to the plate and demand action. NObody else will do it for you!
