Tag Axle Dump

What is the purpose of the Tag Axle Dump and why and how is it used. Looking at the American Revolution 42G.

Thanks

Jim

The idea is to reduce the "scuffing" of the tag tires during very sharp turns. The coach will pivot on the drive tire so the tags get dragged sideways a little. When set to "Auto" the tag will automatically dump when the coach is put onto reverse. Unless you have your transmission programmed differently, and you can, the tag does not dump going forward. For really sharp forward turns, like parking, you need to manually dump the tag. The tag will auto inflate in drive if the speed exceeds 8 mph.
I keep my tag dump in auto and only sometime manually dump for sharp forward turns, mainly because I keep forgetting.

As stated those sharp forward turns are low speed only. This is when the "scuffing" occurs, especially on blacktop.

Also it it amazing how much tighter it turns when the tag is up.
I don't think mine has an auto setting. Just off and on.

The control modules can be programmed to do several things. I found that if I dumped the tag to make a 90* turn, it was inflating before I had completed the turn because I got to 8 mph. So I had the modules programmed to dump the tag when the directional signal was used and the speed was below 20 mph. They will re-inflate once the speed is up to 20 mph. I have a pair of LED lights on the side panel that light up when the tag is dumped, so I know the program is working. The tag operation is now automatic if the directional is used.

We just camped in grass at the National FMA/Fmca rally, dumping the tag puts more weight on the drive axle and increases traction.

On a typical 42-44' tag axle coach dumping the tag transfers weight from the steer and tag to the drive. I have found through several weigh checks that for every 1000# taken off the tag, 160#s comes off the steer and it all goes to the drive. So if the tag weight goes from 7000# to 2500# (that's about what it is when dumped) you have added 4500# + 700# from the steer or 5200#s to the drive. That is where the extra traction comes from. I know, my wife tells me I'm too anal, but I'm retired and have to have something for my mind to do or I would get into trouble.
