I have thought about changing mine, just on principle....mine is great for gun forums (and that's my name on a couple of gun forums) but no so great on a truck forum.
I would change it to "Lock Patient," "Happy Old Man," "Regular-K," or "Ford Truck."
JUST KIDDING!
I would change it to "Dad's Truck" or "Money Pit," something very accurate for my case.
But my name is working and people know me as that so I will stay.
