After reading this I called road master I have an all terrain bar. Their technician told me the life of a bar is 70,000 miles or 10 years. If it has been serviced regularly it's is still the same. Did not offer much conversation or explanation.

I called blue ox spoke to their technician who said life of their bar is 100,000 miles and or 10 years as well. He explained that service every 2 to 3 years is necessary and the life of the bar will change based on environment and terrain traveled. Failure happens due to metal fatigue and welds breaking. The aluminum bar has a shorter expected life of 7 years with the preference of conditions. He also noted that very cold weather and salt air environment will shorten the life as well.

I need to place new plates on a new vehicle. My current bar has well over 50k on it and is 7 years old. Hmmmmm what to do!
