In that case, Costa Rica would be the best bet.
We gots to have booze, if only as a disinfectant! Heresy, I know, but anything ferments - especially coconuts.
Warm - so minimal fuel needs other than cooking. Good climate for sugar and spuds (corn, I don't know, but probably with a bit of extra work.) Plenty of sea life, and enough rain to be water independent. Like your idea of motorbikes or trikes - cheaper to run, easier to repair, especially grabbing a couple of old Nortons.
Medic of some sort would be needed for sure.
Shooting though -
Long gun, fine. Hit what is aimed at, well usually. Shotgun - better. Handgun, couldn't hit the floor if I dropped it.
Wife is a good shot - but she has a problem. She's a liberal.
This is rather fun!
