Tag Axle and storage/parking

When you are parking your unit for a time (whether at camping, at home during the summer, or winter storage), do you keep the tag axle up or down? I can't seem to find any actual recommendation on this, and can sort of see a bit of both sides to it.

If you keep the tag axle down, you're keeping pressure on the air system that holds it down for a longer period without any movement.

If you keep it up, you're putting extra pressure on the main dually tires and suspension (although while parked at home/storage the unit should be fairly empty, but still)

Thoughts/recommendations?
  • Tag always down except in slow speed tight cornering. You don't want to leave all the weight on the duals for long periods.

    Sure, the Tag will drop with no air pressure but if there was no air pressure pushing it down there would be no lift or support of any weight. The Tag would only be carrying its own weight. It must have air pressure to carry any additional weight and to take weight off the drive axle.

    That said, when parked for a long period, I dump the master air suspension which removes air bag pressure from all 3 axles. The extra static weight on the drive means nothing while sitting still.
  • Mine is all manually controlled. No fancy system to have it automatically engage at 10mph :)

    While Mike is certainly right, my tag doesn't actually lift, if I flip the switch to 'exhaust' it will drain the air tank and take the pressure off the tag (and put it on the dually).

    One thing for sure, if I hit the exhaust switch, and let it drain, definately a pretty good lean backwards on the unit :)
  • Definitely down. And it doesn't require air pressure to hold it down -- gravity takes care of that. It will always be down by default, unless you or the coach's automatic system pulls it up, as in low-speed maneuvering.
  • Down is right. Ours will automatically lower if over 10MPH so I have to keep an eye on it in tight turn CGs and speed so that when I get to the site it is still up before making any tight backing turns. The "up" alarm is another warning.
