Towing four busas and all our gear in a 8' X 20' enclosed trailer with a 2007 Ford F-150 4X4 that will average 10 MPG. Right at 1000 miles one way from Kansas City to the Gap. Lets see, if gas would average $3.50 a gallon, that would be about $350.00 one way!
Now lets look at it without the trailer. 1000 miles on a busa that would average 35 MPG = approx 29 gal of fuel X 4 hayabusas = 116 gal. X $3.50 a gal. = $406 plus rear tire wear. So looks like taking the trailer will save about $112 plus tire wear on the busas plus we will have all our gear, tools, spare tires and wheels and other spare parts.
