Where to buy maxwell start module in canadaI live in canada but drive to the usa in michigan frequently. Can i buy a module there somewhere.
Answer to "airtabs or vorblade what is working best?"air tabs only work on a tractor if the gap between trailer and where the air tabs are installed on the tractor is less than 40 inches. if the gap between your tractor and trailer is bigger then you need vorblades, they promote a 10 to 12 ft vortex. now in saying all of this, i have used both air tabs and vorblades, i like them both, they kept the snow off the back of the truck, therefore i know they both give better fuel mileage, i would say i gained about 2 percent fuel savings, i did not buy them for the fuel savings, i got them for the more stable ride in the wind and for keeping the snow in the winter off the back of my truck.
