What I was thinking was that using the fuel cell to recharge batteries might be a better idea than the solar system because it works 24/7 and is much lighter than the solar array.
You would still need your generator to power your air conditioner.

Also not sure that the fuel cell is available in North America yet.
I am going to send them an e-mail to find out.

Something I've seen mentioned here is mounting your panels on your truck. If you have a shell on the bed of your truck you could mount the panels up there. If not you could buy/build a bed rack and have a lot of square feet of panel up there. It would be easier to get to tilt and position the truck for optimal sun sucking when the trailer is in the shade.

You would lose your battery charging ability if using the truck, unless you put your expanded battery bank in the back of the truck, which might be a good thing for an overloaded trailer anyway.

I'm not crazy about that option, but everything is on the table. BUT doing that would require a new heavy duty cable from the truck to the camper AND the increased air drag would present a perpetual MPG issue. Those are serious issues for me.

Rodney my panels on the Tradewind work great. They are mounted like you want to mount yours. There is no wind resistence that I have noticed. You saw how I had them mounted at the balloon fiesta. I wouldn't bother with a MPPT contoller I'd go with a PWM controller. The MPPT is only cost effective on a large solar array. For the Limited I'm going to try the Xanrex C35 Solar controller . The panels are in the back so you can't see them very well in this picture but these are 130 watt panels , for a total of 260 watts.

They are Sun 130 31 x 42. They cannot be used on a grid tye system but for an rv system they work great! The site I got them from is Solar Panels : Solar Panels Direct $0.98 per watt when buying two pallets

Here is a view of a 43 watt and 75 watt panel on the rear roof of my 21' Sovereign, the panels are about 21" wide and 26" and 47" long, there isn't a lot of extra room up there:

I didn't want to drill any holes in the roof skin, so I made some 2" diameter aluminum pads with 1/4-20 tapped holes and attached them with 3M 2216 epoxy.

Back to thinking solar again, the new 100W panels are looking good.

Maybe this system with a second panel? Thoughts?

Boondocker I just ordered a system from them this week. I expect to get it on Monday. They are great folks to work with and have a good rep here on the forum. This system I got (covered on another thread here on the Airforums) is a 100W panel and a 50 watt. I may add another 100W later, after I see how this meets my needs). I substituted the Sunsaver 15 for the HPV 22B as I wanted the remote control head, and the Sunsaver should be all the controller I will need with my setup. I hope to get it up an running over the next couple of weeks as time and camping trips (2 more this month) allow.

Here is the other thread with info about installating a system and my comments about what I am getting. My comments are late in the thread, however, early in the thread you can see the installation of a system sold by AM Solar.
