It is actually different from that. My husband looked at it, the filter is even different. I think he is getting a bit frustrated, he always changes our oil. He is mechanically inclined (he owns a metal shop). I told him I would hop on here and see if I had any luck finding out. Might have to break down and take it in.
Thanks!

Undo 4 (I think) bolts on the aft portion of the skid plate. The plate will then pitch forward under the truck. Near the pivot point, there is a cartridge housing. Loosen just like you would a normal oil filter canister. Replace the filter element inside, reinstall. There is a key on the housing that tells you how tight to get it. You just have to move that key past the tab on the engine side when you have the housing flush.
