Need an opinion on buying a different snow hauling truck. I have a single axel now with a 14’ box but it’s to small to make money for the city since they charge by the cubic foot of the box. I found a 18’ c70 Chevy tandem but it is not a twin screw. Will that be a problem since it’s not a twin screw? A buddy said it might not work very well. The guy took really good care of it and it’s all DOTed so should be good to go just need taller sides.
