The Class A we had (an '02, but can't remember the brand) was equipped with a built in generator that took its gas from the vehicle's tank. It had a higher suction inlet than the RV's fuel pump, so the genny couldn't run the tank dry.
For comparison on the weather, our highest wind speed yesterday was 10 knots and we got 0.2" rain (the first for several weeks). So much for the nickname "The great Northwet". We're in Anacortes, which is on Fidalgo Island, off the northern coast of Washington State. It's the only one of the San Juan Islands with road access to the mainland.
The only downside is the risk of earthquakes (we've had one minor one in the 49 years we've been here, centered about 150 miles to the south) and volcanic eruptions. Mount Baker is about 60 miles away, Rainier about 150. Both are visble from the area, but neither has had a big eruption while we've lived here.
