Fiberglass VS. Aluminium

Hello all
my build is getting closer and closer to starting every day. I go to pick up the HF trailer tomorrow. The design is almost complete (in my head at least), but I am still debating the exterior finish.
I have not decided to have a woody or an aluminum skin. If I would do a woody I would cover in fiberglass as per Steve's manual. I am curious as to which method would have less weight, assuming the same sandwich wall construction. Also, is there a difference in long term maintenance between the two?
Any and all comments are welcome and as soon as I start to put together the trailer I'll start a build journal... with pics.
