Yep and if you have the GAP tool it would be better to just add height to the bases and remove when hitting the tarmac again.

 

Agreed ....and that's what I do.

 

The most compelling argument I've heard is to enable it before a deep water/mud crossing to eliminate the possibility of the computer dropping height at an inopportune moment. Anyway, not really advocating for it, just another tool in the toolbox.
