Our coach came with a 30 Amp Shore Power connection. This is generally not a problem when limiting your power usage to only two high amperage draw appliances, i.e. air conditioner, water heater, hair dryer, microwave, electric space heater, etc. This was only a problem for us when using two space heaters when camping in cold weather. It is easy to forget and turn on the microwave.
I have noted that several people on various forums recommended using a separate drop cord out to the 20 Amp plug found on 99% of power pedestals. This adds an additional 20 Amps of power for use in the coach to power your space heater or whatever.
With this in mind, I decided to make this a more permanent addition. Instead of using a drop cord, I added a 20 Amp male twist/lock connector with a cover to the side of the coach and added permanent GFCI protected outlets to the bathroom and washer/dryer compartment to more safely use this additional power.
Here is a link to the installation.

While we don't have the 100 Amps of power that a 50 Amp rig has, we now have 50 Amps of power which is adequate for our needs.
