Question 30amp converter? to common plug?

Is there any such thing as a 30/50 amp converter to a common 110/220v plug? We've purchased a used motor home and find that not many campgrounds list (or even have?) the ability to use our 30amp power. We would also like to hook it up at home and need to know the hardware, etc. in order to use the A/C......

yes there is such a thing as a 30/50 adapter (don't invert that). They are often called "dog bones". There is also a 30/20. a few calls to your local RV dealers or surfing rv websites will turn up what you are looking for.
On the 30/20. Check the circut your outlet is on that you intend to plug this into at home. What size circut breaker is it on? A 20 and you should be alright, (as long as it is not sharing the circut) you just wont be able to run as much at once as on 30 amp service. A 15 will give you trouble as your roof air can draw enough amperage on its own to trip that breaker on a hot day. Add to that the draw of the converter, any tv's,vcr's, the refer, water heater, ect and you get the idea. The best thing to do is install a 30 amp outlet just for the RV. you will then be able to use it just the same as when you are at a campground as far as electrical consumption is concerned. But that is not always easy or cheap. If you goto the expense of that then you might run a 4 wire just as if you were going to run a 50amp service and maybe save yourself later if you move up in the RV world to a unit with 50amp service. The conversion would then be simple from 30-50amp service.
In any event, only use an extension cord if you have to. And then only as long as need be. Whatever you do, DO NOT use a 14 or 16 guage extension cord. You will need at least a 12gauge or better yet a 10 gauge extension cord. (Heavier yet if it needs to be more than 25feet) In this it might be best to make one of the needed length. Most hardware stores should be able to sell you what you would need( 10 or 12 -2 stranded wire and ends).
The problem with the lighter gauge cords is that they are not made or rated to carry 15 or 20 amps and thus become the weak link in the circut. I have rebuilt compartments, and rewired units due to fires and or melted wirirng from these lighter cords. Most of the time they are too long and the excess is coiled up adding to the heat problem. I know that lots of people "get away" with this, but many also don't get away with it. You don't want to be one of the ones that wish they had spent the money to buy a cord of proper gauge.

just one other thought if you decide to install a 30 amp outlet. you might want to speak with someone locally who knows the local codes. The outlet will require an entire circut and depending on your setup, local codes may require you to do this or that to make the circut proper.

That doesn't sound too bad-Thanks!

We've got several open circuits on an additional fuse box we installed recently. We should be able to make something work.
