Dry box in Cat frame sizing

I am going to order a dry box (finally) to replace my "semi-dry" 48 gal. Action Packer. I am also considering versatility within my current frame. I have a 4-bay Down River single rail Yampa 2 frame (2" diameter) plus a trailer frame with an opening of 18 1/2". I'm thinking of a custom box from Down River that will fit in the trailer frame and sizing other bays similarly or moving cross-rails if needed to be able to fit it under the Captain's seat or as passenger seating in the front bay. 20mm ammo boxex fit in 18 1/2" so it seems like a good width for vesatility.

I'm struggling with the best width and depth below hang-tabs to order. If I decide to move it into a bay where I will have bottom rails, is it better to maximize the width between the tubes and get a box 4" wider to sit on top of the bottom rails? I could also have a cross-bar beneah the box that wouldn't need to moved. The tubes are 26" and the rails drop to 12 inches so I would not have a rubbing conern since the tubes would be diminishing to to top rail. Or, should I order a box that is 4" narrower but 2 inches deeper and move any crossbars so that it will hang to the lowest bottom rail height.

My brain is telling me I will maximize space by hanging the box to the bottom heigth of the rails (2" X 38" X 18"" vs. 2(2" X 10" X 18").

Please let me know if you have have made a decision similar to my current dilemma and if you are happy with your choice. Thanks!

Why get one box when you can get two for twice the price?

I'm trying to visualize your problem. 2 X 38 X 18 or 2 X 10 X 18 isn't making sense to me???
I used a 66 inch wide NRS yoke cat frame, which is 33 inches between tubes, or 33 inches between the center of one bottom rail to the center of the other. I used a 34 inch wide dry box. I went with a 13 inch tall box, with the hang tabs 3 inches below the top, which left 10 inches below the cross bars. With that height, the box didn't sit on the bottom rails, and because of the diminishing tube size that you mentioned, the boxes didn't touch or rub on the tubes. I have two dry boxes, one is 16X34X13, and the other is 14X34X13. I'd say, grab a tape measure and see what the width is from the center of one bottom/drop rail to the center of the other. I would call that your max width if you want your box to sit on these rails. Then figure the depth from the top of your cross bar to your bottom/drop rail to get your height. It's up to you, whether you want the box to sit on the bottom rail or not. I chose to have one inch more width & raise it up slightly off the rail to avoid any rubbing. I hope this helps with your question?

I purchased a custom dry box from DRE this fall. I could not be happier with the product. Bombproof.

Exactly! The larger box is the one that would drop two inches deeper but be four inches narrower to fit between the bottom rails. If I were to line cans of beer across the bottom (2" X 38" X 18"), versus stacking them in the four inches gained (2(2" X 10" X 18")) in a wider but shallower box, I think I could fit an additional case.

Thank you everyone for your input. I know the end products will be great! I will try to not overthink it and place an order soon.
