2x8's form the base of the drawers.
I'm 6'3" and 230lbs - needed something substantial.
Plus 2x are cheap, easy to work with and available.
I could have gotten some more drawer room with 1x, but not as sturdy.
Plus didn't really need it if I was using tubs vice trying to maximize the area for drawers.
x8 I thought was a good compromise on height for drawers with easy to find tubs.
Tubs are $15 Target brand - Dimensions (Overall): 35.87 Inches (L) x 16.65 Inches (W) x 6.63 Inches (H).

Here is a picture of the underside in case you are confused. You'll see I also threw on a strap of thin aluminum I had lying around to further ensure the supports didn't move over time - probably not needed.
I'm pretty happy with this overall.
Best Attributes:
- I can get the drawers and tubs in and out in 2-3 minutes - loading up on mulch at Lowe's or getting big items is not a issue, just throw this in the garage for the day.
- Carpeting and padding - slept on this a few times. Sure I used a versa mat and a bag, but the extra padding was nice.
Easy Improvement - could have used carpet that matched the black interior and this would be almost invisible looking in the windows.
But that carpet cost 3x as much and I was being cheap.
As is, the grey doesn't really attract attention.
