what about when towing in upwards of 2 tons on a trailer? im stock right now, but how how much would it effect the leafs with that much weight with the shackles? i usually get a few loads of mulch a year and if its wet, it weighs around 2 tons. i also haul my motorcycles and tractor on ocassion as well. i usually make a trip to the dump once a week with trash and dead, wet grass also. how would frequent towing effect the shackles compared to AALs?
