I've been looking for a bed topper for my 2010 2500 Mega Cab (short bed - 6'4").

I've found one about 3.5hrs away that came off of a 2015 Ram 1500 6'4" bed.

I can't find much information online other than Dodge calls the 6'4" for the 1500 a mid-size bed and the 6'4" for the 2500 a short bed.

Are the 6'4" bed on all the 4th gens the same?

I don't want to drive 4hrs one way to find out it doesn't fit.

Thanks!
