As a construction worker traveling alone I was ask this about the ten year rule more than once.As soon as they saw my rig I was welcomed.They saw me as maybe a rough neck until further checking and was going to use that rule to reject me.My rig was under ten years old and really well maintained.Usually after staying a period of time and work was on down the road and I was checking out they most always welcomed me back.I have seen many parks that needed the rule very badly.I wish I could tell you about some places I would move out of the first break in my work schedule.In about twenty years of be there miles from home at seven tomorrow AM.No one wants trash around them.Been stuck in some bad deals a time or two.Pull in at night,be on job at seven AM next day,then work ten to sixteen hours per day for a few months.Thats when you wished they had the ten year rule.(my rant)To use it to reject some junkers.
