When I am on the interstate in my car I usually am found in the high speed lane keeping up with traffic. I just love it when a big rig decides to get in the passing lane and goes UNDER THE SPEED LIMIT. That fries my butt. So I DON"T YEILD and get past them so they can putter in the high speed lane without me behind them.
Now, when in my M/H I STAY in the right lane unless I am able to pass the vehicle ahead of me without slowing traffic in the passing lane down. I wait until I see that there is little or NO traffic in the passing lane before I pass.
Most people in the passing lane are going around 75 to 80 MPH. I don't want to or need to go that fast in a big RV pulling a toad.
