Having done both, I would say that gas is much simpler from a practical
point of view, and a little worse from a permitting point of view.  I'd
rather go through the one-time hassle of the permitting rather than the
continuing hassle of maintaining diesel facilities, any day.

That's true, though it's never been a sufficient difference to be
problematic for me.

Yeah, it's no problem.  Certainly no different than deisel in a metro
area, and much easier than diesel in rural areas.  I've never had to ask
for a rush delivery, but I've always been offered delivery the same day
I've called, and I believe the contract guarantees four-hour deliveries
when we need it.  My tank is a 96-hour supply, so that's fine for me.

The only difference between the diesel and gas genset is the carburetor,
which is just different, not more expensive.
