2horse, I'm very satisfied with it. It is plenty rigid for making a tilting setup. I considered it too but mine is up under the front lip of my roof box a couple inches so that won't work. I bought it on Amazon and many here have as well, it's pretty much the most popular one on there now and you can read thousands of reviews. No need though, really, it works great! I think 200 watts is the ideal setup, but I have no real estate for it. My 100 watt setup, with the kit-supplied PWM controller and 2 group 31 AGMs (I don't remember my amp hours on the batteries) will run my fridge for 4-5 days with average sun and clouds before it's dipping to around 12.2 or so when the fridge compressor runs. That's when I plug in and charge for a night. If I drive the van regularly I can probably go indefinitely, but I say 200 watt is the ultimate because you could save the time and trouble on the tilt setup and soak up plenty of power without tilting them. I also think with regular usage of lights, furnace, etc. 200 watts with some daily sun or driving the van some would balance perfectly.
