How do you make money with my pickup truck?

I started working for a Bounce House company (moon bounce, jumpie, bouncie, whatever), I didn't realize how many of these companies there are out there! Most will pay you like this: set-up + pick-up + mileage = Hard Earned $$ I make an extra $100 or so (after accounting for gas) on a Saturday and get a great workout, many of the "jumpies" are anywhere from 200-800lbs!
