Im looking at the Demco DM6012 and DM6076SL-FLAT. What are the mounting dimensions for the rails. I need left to right, on center bolt up and front to rear on centers, for each bolt hole please.

I went out to our warehouse to take a look at the Demco SL Series Base Rails # DM6012 that you referenced. There is a set of 3 mounting holes at each end of the rails. The holes are spaced apart 4 inches on center, with a distance of 10 inches between the 2 sets, on center. From the center of the last mounting hole to the edge of the rail at each end there is a distance of 3-1/2 inches. I have attached an image to assist.

The left to right measurement on the bolt holes will be dependent on the hitch that you are using. For the Demco Hijacker SL Series Flat Deck 5th Wheel Trailer Hitch # DM6076SL-FLAT that you mentioned this distance will be 30.3 inches on center. I confirmed this with my contact at Demco.
