Glad you are well and adapting.
If buying a back-up generator for mainland use, I'd strongly suggest natural gas fueled (if available). The lines are always buried and more importantly, there may be residual pressure in the delivery lines for 3-4 weeks. Even if the 'local' compressor station is knocked offline, remote stations can still push fuel to end-users.
I'm not aware of current natural gas availability in PR. I know there is a LNG receiving terminal/re-gasification plant in PR and they have a NG delivery grid (no idea of extent). I think there was a plan to extend this grid (pipeline) to VI, but obviously, if not already in place, it won't help current situation.
