I find this a very interesting topic. It has been discussed before in other places, but is deserving of a revisit. I have watched with envy as other coaches of my overall dimensions have made turns that I cannot. As mentioned, many Prevots just lift the tag axle and decrease their turn radius. I watched a VanHool pull into a parking spot between two other busses I could never have negotiated with my non-lifting tag. I even saw a Holiday Rambler lift its tag yesterday.

The newer coaches with the steerable tag have a reduced turn radius, but one must be very careful as the rear will swing right in a left hand turn enough to cause trouble if you are say, close to a wall.
Tuga mentioned the air in the tag and the need to wait until it is exhausted. That is a good point and I think if I remember correctly from air diagrams provided by Steve and Michael, the pressure is normally the same in the tag as the drive axle bags.
My Newell owner's manal does not really suggest dumping the tag for turning, but rather only it a special situation where additional traction or axle weight rating may be involved. If there is anyone that routinely dumps the tag bags I would like to hear all about it.
