Usually the state law is move over or slow down If you cannot change lanes safely
You don't have to get defensive Jake there are big truck idiots you know just like van idiots, straight truck idiots
The problem is, of course, the 5th wheel campers and motor homes aren't involved in a high percentage of accidents, and the ones they are involved in don't usually kill everyone but the driver. That's why they aren't regulated. It's also why cargo vans aren't regulated. As soon as vans or RVs start posing an unreasonable risk to the driving public, they will be regulated. Until then, you loggers will just have to continue to sulk and pout about how unfair it is.
