So your answer to the question isn't yes or no, but that it is most likely a complete waste of time ?
Anders, safety checks are never a complete waste of time. I do a walk-around of my entire rig every time I stop. I feel the hubs, tires
, and wheels as a comparative check for temperature as any one of them that's comparatively warmer may signal a problem. I found that the "D" range tires
that came on my Excursion nearly had sidewall failures when I towed my 34' Airstream home several years ago by doing a walk-around at a gas station. The last 60 miles home were scary, but at least I was anticipating a failure instead of having one out of the blue. Fortunately they didn't fail and I made it home, but the tires
were replaced (before the Firestone Excursion recall
, BTW) immediately.
I check the hitch assemblies for tightness. I check the receiver assembly on the truck to make sure it's not moving (broken or loose mounting bolts). Occasionally I'll "wiggle" the tires on the trailer to check the bearings. I may not do all of the checks at every stop, but I always make sure I do a walk-around.
There have been a number of other items I've found over the years by doing exactly the kinds of things you suggest.
I would say, however, that a failure is less likely after the first thousand miles on a new trailer (after you are convinced that all the running gear was assembled and is working properly) and you won't be likely to see a wear failure for quite some time, unless some component just plain fails.
Regular annual or bi-annual maintenance should be sufficient for you to have worry-free travel.
