I did not come up with the idea of two sets of torsion bars. I talked to Reese Tec support on two occasions and this was there recommendation. I also talked to Andy from Inland who you may want to discus the issue with. In any case I think you will find that conceptional the different bar ratings are available for a reason. They are defiantly adjustable within a range by changing the # of links dropped but a 1200 lb set will transfer more than a 600 lb set! I carry motorcycles and scooters in my 1500
Avalanche with my 1977/31. This rig is at the limit and the lighter the TV in relation to the load the more important the weight distribution will be. Depending on how I am loaded I switch back and forth. If your load remains the same a set rated just higher than your tongue weight is probably appropriate. Although a 3500 truck or a 1500
truck with the same trailer would use heaver bars on the lighter TV a nd less with the 3500.
