Thought I'd share this with anyone interested. It's been talked about before but the threads are very long and tend to stray off topic or become anecdotal. I recently installed these on my 2008 2720:
Micro-Air Easy Start 364 (install time - 1 hour):

Hutch Mountain propane conversion kit (install time - 1 hour):

I can now start and run the A/C on a Honda EU2000 on ECO mode using propane, NG, or pump gas like normal.
Before this, A/C was only a plug-in or huge/heavy/noisy generator option.
