I see it as it's better to have more than not enough. And yes slo-ride I agree 100%....well see the first I guess box that I built I thought would be ok but I was definitely wrong lol. And i've never used 2x4's to build a shell. So that was my first time, and I came to the conclusion that my car is to small to be able to use them and still have a large amount of cubic feet. So through trial and error I'm on the third design. But I do plan on thoroughly thinking this one through. And I'm going to attempt to make it in sketch up first lol. But either way, this time I also have all the interior taken out of the back this time. which gave me a few more inches that helped drastically....so with it stripped in the back my new dimensions are 44 wide then it tapers in the middle to 48, then it's 38 inches tall, 28 deep, that leaves me 10 inches in the back for my tool bag and a few other things. And 10 inches on the right side in the front above the wheel well for my four batteries. Cause I have nowhere to put them. That's the only place I could think of.
