That's a good indication that you should never visit that park again as they simply do not understand the product they don't allow. Many don't allow you to use a combining device (plug one into a 20amp and one into a 30amp (or 2 30's) and provide the RV with 50amp-60amp) but the autoformer does not do this and does not add an excess strain to the RV parks electrical system. There would be exactly ZERO reason for any park anywhere to disallow the use of this device. It just keeps the RV parked in their site safe from the crappy service they are providing. If they are not providing the crappy service and there is good 110-120V service available then the autoformer would actually do NOTHING!
