Hey Buzz, thanks for those links! Now I can't decide whether we (my Dad and I) should build the shelves or just buy 'em.

New Interior Dimensions: 25" Deep x 30" Wide x 13.5" Tall
I got the ideas for the new dimensions from those trays, Buzz. The website said that the dimensions for the trays are: 12.5" Long, 7.5" Wide, and 2.25" Tall.

So, with my current dimensions, I will be able to fit 6 layers of 8 trays (4 Wide, 2 Deep)..

Current thoughts on new dimensions?

Thanks for all the input! I really appreciate it!
