Actually, it's not for shipping.

I am building a flatdeck (70" wide x 72" long) with steel frame & wood in the middle and also a removable aluminum frame camper that is bolted on top.

My current stock xcab with box & fiberglass topper gives me ~ 50/50 weight distribution...

I want to calculating the minimum weight the flat deck can have to maintain the weight distribution, & the maximum weight the camper can have for not overweighting the rear.

It's a 22re afterall, the whole thing has to be light/low enough to maintain 20-22mpg and uphill-dable on hwy in the mtns.

Why flat deck, because I need it for contracting work hauling stuff and the box is not up to the task.

Which also brings me to my other post question about tires.

I currently have 72" width stance (Outer tire walls) with 32x11.5 MT on 3.75bs rims. I like this because it's even stable without swaybar.

After using that setup for a year, i'd like run skinnier tires for better gas mileage/threadwear/winter conditions. Since i have 4.88, my options are 33x9.5 AT or 33x10.5 AT.

Using 33x9.5, my width stance will be down to 70" using 3.75"bs 15x8 rims & 68" with stock rims. Compared to 72" currently, is 2" or 4" are whole lot difference in vehicle handling, both hwy & off-road (no-rock crawling, just dirt/mud?)

With the camper on, is 9.5" sufficient for most of the hwy driving?

I have no idea, i think i'm being too paranoid... <img src="/forums/images/graemlins/zombie.gif" alt="" />
