I think it was Hurricane Gustav in ‘08 that really did a LOT of tree and fence damage to Baton Rouge and took out lights for about 4 days (a few weeks in some locales). We went and brought the TL from storage. Its fuel was not full, and there was no fuel w/ no electricity to run gas pumps, so we only ran the generator a couple days for several hours of cool AC. Used boat battery and an inverter to run a fan all night and slept in house, then recharged the battery while running the generator in daytime. Put food from house in the RV fridge.
Now, the RV is at house under a shed (sig pic) and we always fill the tank before hurricane season.
