Nice rig, Chris. Some of my buds run around with stuff piled in the back of their PUs or crammed into a small car, but I'm too fussy for that. We used to put the tips up the shaft like yours, but with CA soft soil it's not necessary. One in a while we have to use a pounder to get started, but not too often. Gravel lots do require a pounder to start the probe holes at all times.
