Okay - for those interested in what Newell has to say - here it is and I quote from the owner's manual.

"Tag Axle Control Switch - When attempting to start the coach moving in poor traction conditions such as snow, ice, or mud, the drive axle tractions can be significantly improved by releasing air pressure in the tag axle suspension, thereby decreasing the weight carried by the tag axle. To use this feature, first, ensure that the coach suspension has achieved normal road height by idling the engine with the leveling system in travel mode. Then, release the air pressure in the tag axle by pushing on the top of the switch marked TAG located on the coach instrument panel. The coach should not be driven more than a short distance in this mode.

If it is necessary to decrease the weight carried by the drive axle to comply with axle weight limits, the TAG axle switch is pushed on the bottom, increasing tag axle suspension air pressure. This transfers weight from the drive axle to the tag axle. It is not recommended to operate the coach is this mode except on a temporary basis."
