For 6 years I drove between CO, WY, UT and NM doing maintenance on 91 building sites, taking care of security issues, and anything from plumbing, electrical to heating and air conditioning. Worked with OSHA and other safety firms for those buildings along with remodels, new construction, additions. I was told by the company I was the highest paid mechanic because of the time spent behind the wheel getting double time on Fri. and Sat. usually working 55-60 a week. Always drove a Ford F450 4X4 van and usually about 4,000 to 5,000 over weight (wind played hell with you in the winter month). We were certified first aid and were told to help anyone we saw in our travels, stop and provide help. The semi truck drivers from the south were always in trouble during winter months in CO, WY, UT and NM. Man talk about the roll overs, would stop and get them loaded up and take the drivers to the next town for help. Those guys would cuse the dispatchers, the state, the roads, their company, you name it, unhappy campers. If one out of a dozen thanked you for helping them, that would be normal. Finally had to change jobs within the company after a roll over with a broken back. We all have good and bad experiences driving over the road, if asked would I do it again, hell yes.
