This is what I use to haul my toys. It's a Freightliner FL70 with a C series Cummins and air ride/air brakes. I don't farm or haul for hire, so it's licensed as an RV. Plates are $102 per year, unlimited weight and range. Insurance costs $300 per year for full coverage, including hotel stays if broken down (since it's an RV!) It's worth it to me to keep the miles off the pickup, and now I'm safe and legal to haul three heavy tractors.
