You bet you can I do
Autoformers come in two flavors (Times several flavors) Installed and portable which is the only two I'll discuss here.
Installed... Out of sight, Out of mind, Theft resistant and if you are in a park that has a policy (I HAVE SEEN THESE) NO AUTOFORMERS.. no problem
NOTE: I do not wish to discuss that policy, if the park has it there is not a blessed thing I can do about it.
With an installed you plug in your cord to the dog bone, Plug into the outlet and it works
With a portable you plug the AUTOFORMER into the dogbone and otherwise connect as normal
if anything it will work better on 30 amps.. And it's more likely to need to.
Home is where I park it!
