Honestly you'll want a dually for that load, folks think there's not that big of a difference between a one ton single wheel and a one ton dually but once you've hauled the same load with both, there's no comparison. The stability and handling difference is huge. I've seen some really long camper/fifth wheel/trailer/boat/jet ski/towing a Jeep configurations on the road, not sure how they're getting around the 65' of just ignoring it. Honestly I didn't know there was a length limit. Hot shot trailers and crew cab one tons have to be getting close if not over 65' I would think.
