1st like Marty sid, they are heavy...limiting you to normally less then 2000 lbs..next while they are not required to scale, the DRW setup is a "trigger" for the DOT enforcement officers to chase you down...i know guys that have had tickets for not scaling..with most of the DRW units being 12,300 now, chances are good you would be stopped sooner or later and more then once.. You get ticketed for failure to scale (even though you aren't required) because the DOT's guy are as well versed on the little trucks as they should be, you will be in court, you will win, but its still time and the inconvenience, but its what it is...
