Davydd is correct in that no panel is going to run AC.
I'm getting 7-8 amps out of my panel on a bright sunny day, aimed toward the sun. That is generally enough to recharge a 1/4 to 1/2 depleted battery, but it will take all day. It's a fairly good match-up to a single battery system. Two batteries may be tough to recharge with a portable, unless of course, you don't draw them down very far.
The panel is fairly large, even folded up. It comes in a soft-sided case. I store it upright (on edge) along with my other gear. It could be stored flat on the floor of the Travato, but you don't want to set anything on top of it. It could possibly fit under the rear couch in a Sprinter Van, but I believe it would monopolize that space and keep you from storing other items there.
In my van, it has to come out if I fold down the bed. It definitely has some convenience issues. So think carefully about where you will keep it before you go out and buy one.
