The electrical problem that I have encountered is when it's hot enough to have to use 2 a/c units the entire CG is using so much power the CG's system as well as the states grid system has to be able to keep up with the demand.
In my 24' Sunseeker I only use 1 15k a/c unit and never had a problem at 98 humid degrees. Its plenty cool enough for 2 people and a large dog.
I have used my Hughes Autoformer a few times to boost the electrical at my CG pedestal.
I protect the Autoformer with the addition of the $100 surge protector then run the $350 surge protector between the Hughes and the rv.
