I guess I'm different. I removed the regulator from my Weber Baby Q so I could fit it with a QC to operate off the trailer's regulated supply. and it works fine. I've read posts from people claiming that this does not let the grill reach full output, and I wonder how they determined that. Mine gets hot enough to cook steaks, burgers, and chicken, so that works for me. The trailer's supply is also enough to run the 30K BTU burners on my Camp Chef for frying fish, so I don't know what more would be needed.

I now have a Keystone Outback, but I try to help when I can.
