2012 chevy colorado bed dimensions. apparently there isn't a long bed option, just bigger cab options
Dimensions WT 1LT
Cargo Box Length @ Floor 72.8 in 72.8 in
Cargo Box Width @ Floor 57.2 in 57.2 in
Cargo Box Width @ Wheelhousings 42.6 in 42.6 in
Tailgate Width 52.4 in 52.4 in
so it looks like neither of these is wide enough to set the tub in the bed nicely. I'll have to see if the f150 or ram 1500's bed is any wider.
The colorado does have a pretty fuel efficient 4 cylinder that still makes 195lbs of torque, so I guess I'm still looking into it
So the debate is, "little" truck with tub on it's side
or pulling a trailer
or maybe bigger truck and no trailer.
