Bed Szes with Quad Cab on Smaller Pickups

I'm trying to do a little research on smaller pickups with Quad Cabs. I'm looking for bed sizes - to narrow down what I'm searching for, I want a smaller PU with a Quad Cab and a normal size bed (6' to 6.5' or so).

My current PU is a extended cab with a truck bed size of 78.8" x 59.6", if I upgrade to a Quad cab I go down to a 64.9" x 59.6" size

I looked at a GMC Canyon Crew Cab and they are 61.1" x 57.2" - even worse....

Anyone no of a small PU with the Quad/Crew cab and larger box???

Thanks,
