Kinda not how that works... Unless what you're really saying is as voltage drops, electromotive force (volts) drops.

A load draws power...power could be measured in watts, kilowatts, volt-amps, kva, etc... The load is the load... so when the load has less electromotive force (volts)...it requires more current (amps) to do the same job.

Power = volts x amps

So, if Power is constant...as volts decrease, amps must increase. Increasing amps above the designed amount will generate all kinds of extra heat, because the wires were designed to handle less amperage.
Correct X2

One more item that some people are not aware of: Motorhomes use Underwriters Listed (UL) residential circuit breakers, these are only rated for continuous duty at 80% of the handle rating (Amps). That means your 30A breaker may trip at anything over 24A and still be performing as designed. This varies depending on the temperature at the breaker location; a breaker will hold its rating at 30 degrees Centigrade, but the hotter the temperature, the shorter time before tripping.
