Like some others have noted, I suspect the long periods of some trailers sitting idle could cause problems. Back in the 80's I resurrected an old open rail motrcycle trailer that had set for probably six or seven years.

Our often used cars and trucks likely never see that situation since they get frequently rolled.
I admit to being one that checks the the trailer hubs, brake drums and tires often when stopped during a tow day. Cheap insurance, plus it's an op to play with the IR temp gun :B
