Unfortunately those companies set the spedos to "62" or what have you and one truck's 62 can be 62.7 and the other 62.5 and thus you have a turtle block. I really wish the slower of the two would just let pedal off briefly but, most of them are steering wheel holders and can't seem to have that forward of thinking. I'd also surmise this comes from the elogs and them wanting to max out their clocks for that CPM pay.
