Are you talking about whether to ground at the individual appliances, or using a two wire system and grounding at a common strip in a 12v system?

Referring to the bonding done inside the electrical panel, and whether or not the 120v is bonded to the trailer.

You should bond (connect) the ground wire to the trailer.  Ground (Green) wire of the 120v to bare metal of the trailer.  Hot (black) and the neutral (white) should never touch the trailer.  This protects you in case some wire should ever contact the trailer, directly or through a failed appliance.  It keeps the whole trailer at ground potential

Location: Minneapolis, MN		Thanks Hoss...I gleaned that from the article.

I'm wiring a Progressive Dynamics 4300....sure wish there was a ground bar for the 12v side....is it "OK" to utilize the ground bar of the 120v side for the 12v? I mean they both have a path to ground.

I may get a terminal strip/block and use that for the 12v ground.

We used a two wire 12v system in a LQ and grounded to a common terminal strip. It works quite well and ensures each appliance is properly grounded.

That's what I did on mine, but the PD 9100 converter was separate from the distribution panel, also by PD.

I like the 2 wire 12v, but there is some factory wiring done that is single wire.
