I have never cooked on the Frontier, but have logged many hours on the Excel 20's. I would think that the Frontier would not be as much of a fuel hog as the E20's, but that is just pure speculation.
I think I'd use a modified approach (based on the info on the E20's) to help you get started. The reality is that you just have to start cooking and tinkering with vents, fuel amount, water (or no water) in the water pan, etc. Once you get the temp control figured out, the rest is gravy.
Good luck and please keep us posted on your experiences with the Frontier.
