A surge regulator fosho. The benefits are that you won't have to listen to anyone b**tch in 90+ deg weather that you don't have A\C 'cause the doohickey 'tripped'. You just have to figure out where to install it so it don't grow legs and wander off.

I have both.Surge is hard wired w/display for voltage inside.Autoformer has helped on numerous occasions due to facilities at campground.I chain and lock it when I use it. Utility is only responsible to meter.I have not seen any that did not allow use but there is a lot I have't seen.
#1, Why would a voltage transformer not be allowed? Because to bring the voltage up for your rig, it must draw a disproportional amount of watts for your use, drawing down the voltage for everyone else.
#2. Another reason for having a good surge protector. The really good ones also test for proper wiring. Some campgrounds have a owner or manager working on the wiring. Illegal as all get out, but saves money. And my surge protector has caught wrongly wired pedestals more than once. I have had to move to a different spot in the campground to get safe electricity. I have a good friend who was talked into becoming a campground assistant manager/maintaince man and was ordered to repair the bad outlets. Knowing this was against the law, he quit the job.
