I am trying to sell my fiberglass tonneau cover and have a potentially interested buyer that has a 2012 SWB ram 1500 and wants to know if my cover will fit his truck. My cover is off of my 2004 SWB ram 1500. Can anyone help me here? I know they show different years online if you order one new, but that doesn't always mean anything. I have not been around the new body styles up close to visually inspect differences or measurement on the two beds. TIA!
