These are a riot, very clever folks. It scares me how closely most of them hit home.
Here's a few more I thought of:
. . .the first picture in your wallet is of your rig.
. . .you've ever tried to change channels on the television in your RV with your hand held walkie-talkie.
. . .you've ever bandaged a cut finger with duct tape, after sterilizing it with vodka.
. . .you know more uses for WD-40 than the people that make it.
. . .you've actually referred to your wife in normal conversation as "DW".
. . .you wear a hat in the CG that you wouldn't be caught dead in anywhere else.
. . .when you have a nightmare, it usually involves "black streaks".
. . .when walking into a rest area or truck stop, you find it a physical impossibility to not stop half way across the parking lot, turn around, and stare at your rig for a second.
