So I recently purchased my first school bus to convert. The purchase was more of a necessity then out of an actual recreational need. I primarily earn my income as a delivery driver. The problem is in order to tow a Prius you need a full trailer. I was wondering if I could kill two birds with one stone by building a two-wheel trailer the tangled up to a 45 degree angle to the rear bumper of the bus. Then there would be only two sets of Wheels on the trailer making contact with the ground. And maybe with a homemade rear fairing, it would reduce drag flow and in essence create a camback. I don't expect this design to give me more miles per gallon. But I do expect it to be a little more efficient than a regular four-wheeled tow trailer. I also have to run this design through and air dynamics computer model. But in theory it sounds pretty sound. Has anyone else ever tried to do this?
