I made a 70W folding setup for under $90.
You can get 35W panels, made in Taiwan, for about $45 a panel, shipped.
Here is who I bought from. If you bid $45, you are pretty sure to win the auction.

They're pretty proud of their 90W panel @ $430 $> . Have you considered making your own folding panel for a lot cheaper? It's pretty easy to do:

DIY Folding Panel

Here's some links to build your own 120W panel for less than half the price of the 90W.

(2) 60w panels for $156
Sunsaver controller $48

Solar panels should do the trick for you but the new Honda and yamaha genies are practically silent if your a few meters away so noise isn't realy an issue

I can relate to your observation about the lack of weather proof charge controllers, and I have a related question. I'm looking at a variety of options to add some solar capability to my TD (which is under construction), but I have zero experience with solar. Regardless of which solar route I take (whether it be a packaged/suitcase option or the DIY route), I have a question for anyone who has some experience with this.

It appears that many of the charge controllers on the market are not weather proof (the Zamp Solar seems to be an exception; the controller is actually affixed to the frame of the panel). Assuming I want to put the charge controller inside the cabin - and out of the weather - I don't see that any of the branded "kits", (Zamp, Renogy, Grape, etc) or any DIY option address any kind of a port that would be installed on the wall of the trailer so the cable (coming from the solar panel) can be plugged into the port - and thereby to the charge controller on the other side of the wall??? The wiring for the other side of the controller would of course be integrated into the trailer's electrical system to charge the battery ... but what about the port? Any ideas on how to keep the controller inside the trailer and be able to plug into it from outside? I know putting the controller inside the box with the battery is one way to go but frankly I don't think that's a great solution since it's not going to be all that weather proof if I'm on the road in a driving rain. If keeping the controller dry is the issue, that's not an ideal solution. Is there a pre-made port to address something like this? (Of course, the more holes you put in any shell, the more potential leak issues you have, so there's that.)

Am I missing something? (other than brains I mean?)
Thanks for any advice or guidance. And thanks for the info posted here already. It's been really helpful.

Moringstar Sunsaver controllers are completely potted and have marine rated terminals. I had one on the back of my panel for several years without any problems.

I just bought the same Renogy 100 W solar system and need to run some trials. I'm a bit concerned that my battery is 3 yrs old now. As far as the charge controller and rain, its tucked in out of the way pretty good I see. Taping some plastic over it should protect it from any splash back too I think
