Could you use the standard 30amp dryer power with a 3000 watt step down voltage converter transformer that converts 220 to 110? We used transformers while I was stationed in Japan.
I'd do a quick search on this. This is a topic that comes up often. The most elegant solution is to have an electrician who knows what they are doing wire up a receptacle. Don't forget to test it with a voltmeter before using it, since there are stories about fricasseed rigs even after a "pro" installs an outlet.
As a second measure, Victron sells inverters/chargers, and I do not know the model, that can take 240VAC, and output 120VAC. Be known that these are expensive because they are made to take two power inputs (generator + shore power) and switch over seamlessly, using the onboard battery bank to keep the 3000+ watts flowing in the interim.
