You would only need one 2ga cable run to the back, and it's probably easiest to run that wire along the underside of the vehicle. A ground can be run along side the positive as well, but a short ground to the body works just as well. Remember to still account for the length of the ground cable when calculating for voltage drop even if your grounding to the body.(just double the length of the positive cable)
8ga for a 30a compressor in the back of the vehicle is OK, not great but it will work, just not as well. The single ground for 2 positive leads is a big no-no, each positive needs it's own ground of equal size to the positive

Thank you knightrider and Duffman for ALL the help
We appreciate er'body's input to make sure Pepe doesn't blow up on the trails!!
We took the following advice:
1. Ran a 2nd ground in parallel (2 red, 2 black - 8ga each)
2. Ran compressor for over 15 mins in 108 degree weather
3. Checked wires for heat
No extra heat, no compressor failures! We.Are.Good.To.Go!
So now..... PICS!!
FiG hard at work.
