Hi Dutch,
NEC prohibits hard wired autoformers in RV's but when the unit is a plug in device, they are not prohibited. This argues for having a plug in unit. I choose to do plug in rather than hard wired.

Be aware that some parks ban the use of "autoformers" (autotransformers), either out of ignorance, believing that they somehow "steal" power, or because either they or their insurance carrier are aware that the NEC prohibits their use in RV's. If nothing else, that could be a factor in deciding between a portable unit versus a built-in one that's out of sight.
