what is the consensus on this combination? - "2001 GMC, 3126 Cat Diesel Engine, 5 Speed Transmission."? - I've asked about gearing but haven't heard anything back yet - bus has just over 100,000 miles on it, tires are excellent including snow tires on the rear wheels - brakes are excellent according to the ad - it's a Saskatchewan bus, so hopefully the gearing is high ( low numbers )
