Commercial drivers at thought to hold you hand at the hub and if you can touch them your good to go. Those guys drive 10-12 thousand miles a MONTH so if it's OK for them why all the heat guns stuff? Most RVs are weekenders and a couple weeks vacation way less than a week on a commercial truck.

I set up a system for a local DOT that "looked" at the temperature of truck wheel hubs as they went through the weigh station. Any guess on how many had no heat on them at all? Probably not much of an issue on an RV, but many truckers have failed trailer brakes where one hub or two have no heat on them at all. Looking for heat is a good way to find overheated but also failed and no heat.

By the way, the truck drivers were very happy to get pulled over for failing trailer brakes. They didn't want to go down the road with brake issues. Often they don't own the trailer. The reason the DOT started the program was because lots of truck drivers rely on their trailer brakes to slow them down, taking stress off the truck brakes.

Technology has really advanced, was that the Fife scale? I was O/O leased to a large company so watched equipment closely as time is money. Company drivers, well that's another story. But we digress PM on this, been off the road a few years.
