T100 x-cab bed dimensions

anyone know the correct bed dimension for the x-cab T? The measurements I have found dont match my own measurements.

I need to know the right size topper I need to look for, as almost every listing shows a measurement, not an application.

I measured 76x66.

got a topper! from an 03 Tundra. It doesnt fit great... its a tad too wide and about a half inch too short... but it looks good enough and it is almost the same color as my T. and it was only $150. Its a Leer brand.

I'd like to know dimensions for cargo reasons. What is length, width at gate, and width between wheel wells?

Width between the wheel wells should be just over 4'...cause you can stick a 4x8 sheet of drywall between the wheel wells and it will sit right up to the end of the tailgate when it's down. ;)

76" x 66" I think is what the box is measured at...but I'd have to go outside in the dark and measure to be sure. ;)

Good news. I'd looked at a Dakota last night that is just short of 4' between the wheels, a bit disappointing. That was 44". I'm driving 2 hours tonight to check out a T100, was hoping these were a bit bigger, couldn't remember which way I'd heard the comparison between these two trucks sizes. Thanks! Here's hoping I bring one home soon... :)
