I have owned this 50A AutoFormer since 2011, works well. I have done this type of install on two DRV's with same AF.
If it ever goes bad I simply would unplug and connect the cord caps.
We have the 30amp version and in parks with marginal voltage, it has really helped.
Even if the park voltage is 105v and technically within spec for the air/con, I am much happier with it boosted north of 115v.
This may be your first experience but it's a common problem at RV parks during peak periods. Harping on the park owner is unlikely to do anything. It can easily run into the 10s of thousands of dollars to address the issue which may only happen a handful of days per year.
PS: Also get a voltage monitor you can see inside, so if voltage gets too low, you can turn off the air/con before burning it out. Under $10 you can get one that plugs into an outlet and provides constant readings.
