I ended up getting this panel and I love it.

It only weighs about a pound. I built a platform for it, taking inspiration from @Alvis:

Flexible solar panel, VHB tape and the poly carbonate sheet are a great combination. You could have it portable, without the aluminum frame, and all together weighing less than two pounds.
As far as quality, we just spent several weekends in north central Oregon, 90 - 100 degree temps outside, bumpy gravel roads, highways at speed, etc. Everything held up amazingly well! Practically unnoticeable when lifting the camper roof.
I might build another for portable and use the rear plug. Though, I'm not sure if I should wire the rear plug in serial or parallel.
