I have a customer who buys and sells antique Airstream trailers. He likes to have them put on a flatbed trailer and transported in and out of the west Los Angeles area to all parts of the lower 48 states. Usually it is once a month delivery. All jobs are paid cash at $1.00 a mile. The trailers that he buys and sells are from the 50's, 60's and 70's and are 14' to 22' hitch to bumper, so you will need a flatbed big enough to fit one on there and you will need a winch to load/unload them with no help from him or his customers.
