One point that was touched on here, but not fully explained regards searching of your RV without a warrant. (Of course, the LEO has to have probable cause.)
Our Supreme Court ruled many years ago that a "movable" RV is not protected from search like a residence, even if the owners are living in it. As long as it can be "moved" within a short but reasonable amount of time, it is not protected. Now, an RV that is not movable can't be searched without a warrant.
Now, if this is confusing, don't feel embarrassed. A US Circuit Court got it wrong and Justice Burger had to explain it to the lower court. If the RV is connected to water, power and sewer, it is movable. If the wheels are off of it, and it would take considerable work to make it movable, it is protected. So, if you're on the road and get pulled over, the LEO can inspect your RV, but of course, he has to have probable cause. If he asks for permission, just say you respectfully decline.
