I built the bed yesterday. Pressure treated 2x12 for the frame rails and untreated 2x10s for the bed itself with 2” angle iron around the edges.
Originally I was going to build the bed so I could carry a vehicle up there. I decided I liked the look of the truck with a smaller bed on it though so I decided against it. We chopped about a foot out of the metal rail channel in the back and built the new bed flush with the rear of the frame. If I’m not carrying a car I can change the rear springs to something a little softer too.
Added some stake holders after the pics were taken and I’m going to add some other details in time. I’ll put some deck sealant stuff on the untreated pine.
We had a weird looking hitch receiver from some old truck so we chopped that to fit and welded it in. Should be able to tow a house now.
