I think so. It reminds one of the early episodes of "Breaking Bad" where the brother-in-law agent had the two cookers trapped in the RV but couldn't go in without a warrant because they kept yelling "this is our domicile" LOL!
Similar thing happened just this week in Denver, cops had a standoff with a guy in an RV. I need to look it up but I'll see if I can post a link.
