Because I am a lumbering bear on the road, I tend to drive much more defensively it the MH than the Van or the Truck. It's nice to have a vehicle that makes people wonder whether you are insured (van). One of my favorite diversions is following an aggressive driver in surface traffic. You know the ones, jumping of the line, racing to the next light, swerving in and out of lanes.
At the next light, I make a point of honking and giving a friendly wave as I sit next to him/her. Not sure they get the message, but after two or three lights with me still there, I hope they do.
