I've been using the same mechanic's floor creeper for probably 20 years. Looks just like the picture below.
It does the job, but there are two things about it I really don't like:
1. The casters are located far enough from the ends that there's an ever-present danger of having the thing suddenly flip upright if you put your weight in the wrong place while climbing on or off it. I live in fear that this will someday happen when I'm under a wing or fuselage - ouch!
2. The casters themselves are rubbish: the mountings are always coming loose or getting bent out of shape, and the wheels are so small that I'm constantly getting hung up on wayward zip ties and extension cords.
Anybody got a creeper they like, that's well-built and won't do the flip-up-and-dent-the-airplane thing?
