i just called trailair for air ride pin box and was told that i will need the tra.pin wgh.for correct sizing. you are correct they have one that takes care of the back and forward motion.
i have an 07 md.3295 with a lippert pin box md. 1116 and was told that the trailair would be md. M19-3G. 3G indicates md. that moves back and forward.
i think my hitch pin wgh. is over 3400 lbs. judgeing how much the truck sits down. the truck is a f-350 drw. lb. 4 dr.
the M-19 is 850.00
the M-19-3G is 1100.00
would you spend the extra $ the M19-3G?
open for suggestion
