I also added a seperate outlet for a space heater, and have been accused of cheating/stealing in the past on this site. The fact is, the places I stay that have electric sites don't charge any difference for a 30 amp or a 50 amp rv. My 5er is a 30 amp rv, and my 30 amp with an additional 15 amp cord don't have the ability to use what a 50 amp rv could.
The only reason I do this is I don't trust the cheap receptacles every rv comes with to run a 1500 watt heater. When I use an internal outlet, I only use the heater on low.
