I asked the Escapees forum tonight if there was some way for me to tap into the 50A outlet on my power pedestal so I could run my heater. The answer I got was that it was possible, dangerous, and expensive. The solution became more and more complicated until someone suggested that I get a heater with a lower amp draw.
Which made me pull out my manual, whereby I discovered that by using a lower setting, I can reduce both of the heaters' draws from 12.5 to 7.5A!!! Talk about a DOH moment that had me both blushing and laughing. Even at a lower setting, I'm still getting more heat from the two of them than I would from just the big one on its own.
I continue to be humbled.
