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...

If you're using *both* cords between the power supply and your rig, a 10 volt drop over a run of 50' is not unusual.
