Good points again. Thanks Brian. Off to Tractor Supply with Lowes as a backup right across the street.That's what I would use for a RTV size load (a single chain/binder on each, front & back). That said, I'm obviously not a commercial/professional driver/hauler. The laws seem to vary state by state a bit. If pulled over, I'd claim ignorance but say you gave it your best attempt and hope for the best. At minimum, I'd carry spare tie-down devices in the bed of the truck and if they will allow instead of a ticket, start adding chains or straps until they're happy.
Next on my list is a spare tire for the trailer. And I have to be sure I have a jack that will work on the trailer in case a tire does go flat.
