Eric, I have always considered a Screwdriver to be a very dangerous tool. Hard to poke an eye out with a wrench or hammer compared to a screwdriver. Glad it wasn't worse!
We get into motorbike/cycle carriage on the main Class C forum. A number of us do it, but not me personally. There's a formula, detailing how many KG will load the rear axle and unload the front, depending on wheelbase, overhang from Axle to weight of Bike, and of course Weight of Bike. What does the Bike weigh, and do you have reserve capacity on the rear axle? My guess is, you'd be OK carrying that bike on either end of your Class C, rear probably better.
