Would just have to calculate it and size tanks. I now have a tri fuel and it runs whole house. 2 AC units, 2 fridges and selected items.
My previous generator running 2 fridges plus window unit would use 15lbs propane in 4 hours. $$$
So figure whole house would need max 10lbs /hour. 3 weeks would be 5000lbs.
This off the top of my head and just an estimate.
Just bought a new home lot so I will size propane for general use and 2-3 weeks outage.next house will have less energy demand.
