We had our need for our TT a month after we bought it with the derecho in June. No power for six days, but we had just bought a generator for future camping needs - just had the need a little sooner than planned. Our little $300 generator powered the trailer, house fridge & upright freezer.
We had all our creature comforts including running the electric oxygen concentrator and BPAP for DH, who could sleep in air conditioning.
My son is still out with a crew working to restore power in the areas of West Virginia affected by Sandy. We are hoping he is back by Thanksgiving.
