[Jack in Alaska]

This event is a RV'ers worst nightmare. My MS has approx. 30k miles on it. I always check the bearings/tires with a temp. gun but it appears that it is not enough. What is enough.?? How do you prevent this?? 100k mile/5 yr warranty but when "the wheels fall off" 100 miles from West Armpit Montana you are in real trouble.
I plan on a complete take apart check up next month on my rig before hitting the road. It also includes 2 new tires to replace 2 original 2003 tires. That is all one can do and hope for the best. I am out of warranty by 6 mo. so like they say......I am my own warranty station.
