in recent years the wonderful world of factory truck ratings has undergone a major revolution .... today's trucks (half ton, three quarter ton, and one ton) carry factory ratings that were unheard of only a few years ago .... the days of "needing" a dually to get the ratings necessary to tow the vast majority of campers is over .... for old school folks (like me) that fact can take some getting used to and often generates a discussions based on emotion and not fact .... given the current payload ratings of one ton single rear wheel trucks, the only time a dually comes in handy is it handling side forces .... other than that, the single wheel trucks come out better .... mileage, on going cost of ownership, traction on slippery surfaces, ease of finding a parking place, and so on .... I tow with a Freightliner Sportchassis, our prior truck was a Chevy 3500 dually .... if I was buying a truck today, it would be a Chevy or Ford one ton, single rear wheel
