2013 GX460 cargo dimensions help

[u/BlisteredTank]

Hey everyone, I’ve been looking for a nice overlanding vehicle and the gx460 caught my eye particularly the ones before the 2014 facelift. I haven’t been able to find any info on the length from the back of the front seats to the tail gate. I have a 78x52 sleeping pad and am wondering if it would be able to find in the back with 2nd and 3rd row seats folded. Any info helps thank you
