I too carry all of the various adapters to support my 30A off-road camper. Strange enough I have used my 30-foot 10Gauge extension cord (10-3) with a RV30A-15A 18-inch long Adapter the most of any of them. With this I can plug my 30A OFF-ROAD POPUP trailer into any 120VAC Receptacle at rest areas, sometime McDonalds, several truck stop area have them scattered around their park lots. One over-night was at a Bass Pro Shop parking lot and the had a large section for over-nighters all seluded from each other using high shurbs and a 120VAC receptacle. This was a better camp site then one we just came from haha...
I am always using the 120VAC Receptacle at the 30A camp sites for doing things on the picnic table or running my oil-filled heater inside the POPUP or my Ham Radio operations. An extra extension cords comes in real handy for doing this and doesnt bother your 30A service at all. Usually all of outstde lightning comes from the unused 20A site receptacle.
I catch heck from the better half keeping all these so-called PLAN B items around but I get to pass on "See I told you it would come in handy" everynow and then...
