Getting more electricity to the RV

Since we have been running two electric heaters and the dehumidifier, we have been tripping the breaker in the RV fairly often.  We have close to 20 amp service right now.  If we had 30 amp service, it would be enough.  So, we ran another extension cord to the inside of the RV and have one of our heaters plugged directly into that.

How did we do this?

We ran the electric extension cord through the storage compartment....

Chad drilled a hole through the back of the compartment...
 

...which can be accessed on the inside of the RV.

Then, he sealed up the hole with great stuff insulating foam to make sure no rodents can get in.

Voilà, we now have another source for electricity.

And, I might add, we are staying very warm in this very cold weather we are having.
