Solar Panels on TM??

Has anybody tried installing solar panels on their TM yet?

I had a cheap solar panel on my pop-up and extended my boondocking by at about an extra day, plus it kept the battery charged when I wasn't using the trailer.

I bought another solar panel for my TM and have been contemplating various ways to install the panel and route the wires.

Before I get started (sometime this spring) I thought I would solicit advice from the TM Collective.

Anybody have any experiences with solar panels they can share?
