re: new construction standby generator question

Diesel is in most cases going to be more accessible both pros and cons to each fuel type you would still need a good size fuel tank and if you needed fuel you could go get it but you need a truck and a tank and go every few days but untaxed dyed is cheaper than dot fuel maybe look at getting a tank for diesel. SHTF you can go get 20-30 gallons in a mini van if you needed to propane nope.
