Some Questions

I am planning on building a teardrop in the next couple of years. I have been looking at builds and lots of pics. I plan on building a light offroad capable teardrop. I will probably go with 5x9 or 10 foot. wheels outside the frame. Yeah that is a bit big, but I am 6'2". I am just stumbled on few things.....
1. If you sheet the teardrop in aluminum what are you using for to "cap" the sides off?? Plus if you lap this with aluminum sides are you over lapping?
2.How do most figure your axle position on the frame.
3. What are most using for mattresses. Stupid thought, but I been thinking a way to rollup a home queen mattress though a small door!!!!
