A single axel air tag can be rated as high as half a tandem dual set up ( when using super singles )
they are very good for high cg applications and in a coach the lack of all that gear noise and vibration is a nice plus !
as far as having extra traction with tandem drivers??? maybe, but probably not in most real world situations ! most of the time single axels have more traction while opperating with realitively light loads !(especially if you have a air diff lock s/a )
an air tag can increase available traction (drive ) if lifted
I am probably going this way cause sometimes we dont pull our race trailer, we just use the coach as a camper alone !
