Are the bed sizes the same for 2nd and 3rd gen quad cabs? I'm assuming there is only one bed length for quad cabs. There's a guy selling a camper shell that came off a 2000 quad cab and I'm wondering if it would fit my 05 quad cab.

 

the beds aren't the exact same, the width is a little off, i can't remember which one is wider tho, i believe it is the 3rds that have a wider bed
