Decided to try a round trip to the road and back. Tweaked the steering parameters and the rover seems to be tracking a little better but still meanders a bit. I'm also noticing that when it does an out and back mission, on the way back it tends to hug to the left of the waypoint path. Not sure what that is all about. There are newer GPS units available now, so I ordered one to try out. If the new one doesn't do much different, I can try both of them. The Pixhawk can use two up to 2 GPS units simultaneously and "blend" the readings for more precise positioning. The rover cut it a little close on the way home but managed to plow over and through a couple of obstacles. 97,101,74,0,B

Just now noticed the poles with wires on them along your driveway. Phone lines ?
If you can use two receivers, I wonder if one of the receivers could be a GPS unit and the other a GLONASS unit ? That could possibly double the number of visable satellites providing greater accuracy.
Gary: There are no poles with wires on them along my driveway. I think what you are seeing is Ben's fence.
Bizmark: The GPS that came with my Pixhawk doesn't have any documentation on what satellite groups it works with - but it does pick up 11 satellites and it is accurate to within 6 feet. The new GPS unit I ordered is supposed to pick up 20 satellites and supports multiple positioning systems - GPS, GLONASS L10F, QZSS L1 C/A, and BeiDou B1. It is supposedly accurate to within 2 feet.
2 feet… that's what al-Zawahiri said… Hellfire R9X, six rotating blades
you are on the cutting edge, so to speak…

Bens fence posts do look like utility poles from the angle of the rover camera.
