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...

I'd look at the connections - after a few minutes, feel the connector bodies - are any warm/hot? You have a high resistance connection. If they are hot, the prongs and/or receptacles are not clean and/or tight. The hotter they get, the higher resistance, the hotter they get until things start to melt.
Like GordonThree mentioned - never use extension cords for moderate to heavy loads while coiled up. I have a friend who needed a 6' extension for a load within the cord's rating, so he used his tightly wound 50' cord after unwrapping what he needed. Yep, he melted the entire mess into a useless tangle of plastic & copper in short order.
