Some coaches offer steerable tags. Our previous Dynasty had a lifting tag that would lower after a certain mph as stated above.
Our current coach has a 'release pressure' tag. It will not lift totally but will release the pressure so that I'm not dragging the tag tires and can make a tighter turning radius. Putting all the weight on the drive axle might be too much, hence, the 'release pressure' tag.
I can see the rear-end drop a little when I lift the tag. There is a lot of weight back there so the drive axle can 't take all the weight.
