Are there any class B's that do not look like RVs?

Because it's quieter. Sometimes I do when I'm moving around but even at most campgrounds (dispersed or otherwise) I put it down at bedtime as it's warmer. When I was in Utah three weeks ago, it was as low as the 'teens overnight. I tend not to travel much in the summers when most others are.

Sorry you're so bothered by what other people do legally but nobody likes to be preached to about what they should do (or not) because *you* don't like it.
