is always the question. Luckily, it is low voltage and you can get along with 18 awg wire. But don't discount the battery option as the battery life can be pretty good and are replaceable. The other thought is that you can start with the battery and slowly run 12V as you do other work or have the time. Somfy.com also has small solar panels that will keep the batteries charged.
Just to be transparent, I do work for Somfy. Somfy makes the motors and wireless controls for a wide range of window coverings, but not the window coverings. These are available from our customers such as blinds.com and budget blinds. You can also check with MCD to see if they offer this product.
This accessory offers a maintenance-free and green alternative to powering motorized window coverings featuring WireFree™ motors. WireFree™ motor is required for use of the Solar Pack. Compatible with existing and new installations and various window types.

The walls of the coach are filled with Styrofoam insulation so you cannot just fish wires through the walls. MCD does a lot of retrofit installations and I was hoping someone that had been there and had it done could tell me where they ran the wires.
