At the "side other house"
or
at the other side of the house?
Can you just plug into a regular outlet with regular plugs?
Your electric will work, but the voltage drop might be a strain on the AC that will burn it up after a while, or the cord might melt where the "gauge" is the least, at the camper outlet, or the house outlet...
What really is happening is relevant to the distance from the transformer at the pole, which is usually at the street. Power comes off the power line, to the street pole transformer, and then to the house. At the house power goes to the circuit breaker box, and then out to the houses outlets. Where is the circuit breaker box? How close can you plug in to the circuit breaker box?
If the box is on the camper side of the house and the 30 amp plug is at the far end of the house and you run from that , then you are running electric from the box, to the far end of the house, and then back to your camper.
It would be better to plug in the camper at the near end of the house, where the box is, and run there than to run the electricity to one side of the house and then back (adding another 100 feet to the string).
The house outlet is not the starting point of your issues!!! The circuit breaker box is (you cant really do anything between the box and the transformer, so just start at the box).
