I am waiting for the authorities to catch up with the bus crowd and "lifting the tag"
If they are castrating the truck drivers for lifting the axles, resulting in the ones that are left being overweight, why not the bus drivers?
Leave the darn thing on the ground, unless you have take-off traction issues.
Still waiting for someone to quantify the benefit. I measured it years ago, and leave it on the ground. Next guy recommends lifting for corners, better come to the table with some measurements...
Happy coaching!
