There is no 300 percent mark up...insurance thats required on those peices of equipment run $1200-$3000 dollars a month depending on the coverage that is required...theres garage keepers insurance, inside storage, $5.00 a gallon for DIESEL not gas....the trucks average 12mpg 16 if they are lucky. With gas going up so does everything else...back up off the towing industry they need to make a living too..next time your in a bind push your car to where it needs to go or leave it in the street and get fined by the city of wilmington. Like i said gas goes up so does everything else so back off!
