Cool shots, Ken. As you can tell from the first shot, the reason he didn't take off was because he was checking to see if lunch had just shown up.
Sidney, I like your idea, but I don't think I'd completely do away with the windshield. I don't think you want to eat that much dust or bugs. You might consider rigging the windshield like they had on the old WWII/Korean War jeeps, with the windshield on hinges, so that you could raise or lower it as necessary.
While you're there, you might as well mount a tripod next to you.
