So, I take it, you are connecting via the 15/20 amp outlet at the campground, due to the fact you ONLY have an extension cord that will plug into that outlet....and maybe your true 30 amp cord to your RV will not reach same pedestal?
What size and how long is this extension cord? Your problem is probably all in it.
Wal-Mart usually has true 30 amp extension cords for your trailer in their RV section in stores, if you are close to one.
