Update on hot hubs on first trip

I made a post a couple days about how hot two of my hubs felt after my first trip with my new camper. I just returned home and measured the temps of each hub with a thermometer after the 2 1/2 hour drive the two on the drivers side were between 100 and 120 degrees the passenger were about 80-10 degrees. My question is I have a toy hauler and I keep it to the drivers side of the garage so I have more storage space is this an issue and would you be worried about these temps or are they ok.
