Got my check engine light problem solved. It was a bad boost sensor. Small repair, under $400 which included getting a few other minor things tightened up. Next chore? Getting my old broken fridge out and getting the new one installed.
I would think a check engine light would need to be taken seriously regardless of the vehicle type. I've never seen an engine light come on and then later go, "Ha ha, just kidding."
Yes you can't see the light, but the problem is still there. Sometime when you least expect it, it's underlying cause is going to make itself known at the worst possible time.
