if your both in 2wd the single wheel truck will get more traction on pavement due to its higher pounds per square inch of weight pushing down on the pavement... with a dually the load is more evenly placed and has less weight on each contact patch of rubber on the ground that will allow them to spin more easily... not saying his truck is stouter but more than likely will get more traction.... that all being relative... i would say yall both set there and put on one hell of a smoke show
... and thats if the chains don't break and kill one of ya and nothing breaks important like your ring gear... ujoints... driveshaft
i seen two boys hook two dodges (both mostly stock) together on pavement (in 4 low!!!) it was a great (but short) show of moronism at its best... it lasted about 2 sec. untill one truck broke the ring and pinion in the front axle
can yall tell i came from a small town with a shallow gene pool... stuff like this was the fun thing to do on saturday night
all the good old boys got good and drunk setting in a field... got to braggin about their trucks and well the rest is history... i had a jeep so i didn't get called out much... although i did drag a nissan 4x4 once in my XJ
