Re: Weigh Stations?
Under Federal Law, motorhomes are specifically described as not being commercial vehicles, so they are generally exempt from any CDL restrictions such as stopping for weigh stations. But some officers may be of a different opinion, not know the Federal rule, or be enforcing some special local law.
As a rule of thumb, if I had motorhome/housecar/camper plates on my skoolie, I would keep on going unless they waved me over. If I had any type of commercial or weight-apportioned plate, I would stop unless they waved me through. As always, YMMV.
Edit: I might stop for "ALL VEHICLES" signage. But I know in at least one state the DMV driver's manual explains that roadside signs reading "ALL TRUCKS MUST STOP" only apply to CDL vehicles, not small trucks.
Someone said "Making good decisions comes from experience, experience comes from bad decisions." I say there are three kinds of people: those who learn from their mistakes, those who learn from the mistakes of others, and those who never learn.
