Wire size on 30 amp RV cables
Do the commercial 30 amp RV cables you purchase from Camping World, Walmart, etc use #10 gage wire or larger? I have 2 of these, both 25 feet long and noticed a 10 volt drop when running the heat pump...

Probably wiring to the pedestal. The wiring run to the pedestal from wherever is probably a lot longer than your cords, and may have several others pulling power from it also. Also, like others said, check and clean blades on you plugs. Also, check you plugs and cord ends for overheating. With that much voltage drop, something is getting hot somewhere. Also, check voltage at the pedestal. If the drop is there, it is a park problem.
