We camp at state parks a lot and have a lot of low voltage problems, especially in the summer. We bought a plug in voltage meter so we can keep an eye on it. It is really hard on your a/c to run it without enough power.
We haven't had any problems recently at FW but my cousin had their power pole to burn up on fire one trip several years ago. The guy who came to fix it said it happened a lot due to the RVs pulling a lot more power than they used to.
