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...

The wire should be #10 in 30 ampere cords.
The problem is likely your heat pump and the other electrical loads.
What is the voltage when the heat pump is not running?
There could be a problem with the heat pump. If you have an Amprobe check what the amperage draw is on the pump and compare it to the specification plate on the unit.
