Dual tandems are rough riding, tow heavy cause the more rolling resistance from the extra tires plus flex more since the frame is alot narrower than the triple(the torque tube helps this problem)
Triples tow and track great, ride smoother, flex less but are hard on tires if not loaded and setup right. First thing to do is know how to balance the load between the truck and trailer so the trailer axles are evenly loaded. I can't even count all the trailers I see going down the road pointing uphill or down hill. Second most important thing for me is to run either load range g Goodyear tires. That will stop the excessive tire wear And peeling.
My personal opinion is the tridem setup is retarded and for guys who need to try and impress people. There is no need for that. Maybe you need a bigger truck to be safe anyway. A pickup has its handling capabilities and the horsepower can deff exceed that. Not to mention you can buy a used stepdeck with beavertail for half the price of the tridem and take the other half and buy a single axle tractor to pull it with
Of course I also drive a semi for a living though so I might be biased. Lol
