Again let's be accurate Frontline will supply a truck if you do not have one and are willing to take a lower pay rate(at least in FT Lauderdale)
They still have techs in that market using their own vehicles and they might be transitioning to a 100% fleet company but at this time they are not
I left that market in October of 2009 Thank goodness Ft Lauderdale is not a very contractor friendly market
Until they transition fully a tech can still recieve a backcharge and in that market they should be fully aware they will sometimes due to their neglegance and sometimes that is just the nature of the business
