I don't use an autoformer, nor have I run across a park to date where I needed one, but in those that prohibit them in their rules, I've found the predominate reasons are that they believe the devices somehow "steal" power, although I've never found a park manager or owner that could logically explain how that happens. The other reason has been possible liability insurance issues because the NEC prohibits the use of auto(trans)formers in RV's, which it does. I have inquired of the NFPA what the reasoning is behind the prohibition a couple of times, but I've never gotten a response.

First question: How do you know you haven't needed one? Unless you have a voltage meter that you monitor, you may well have had 104v power and were slowly cooking the air/con compressor but it may not fail until months later at another park with good power.

We didn't pick up an autoformer until we had low voltage kill and air/con unit. Then we started monitoring and found it surprisingly common to have low voltage on hot days.
