One quick update to make.... my wife got me out of bed early Saturday morning and said, "Let's go cut the bed mat I bought you for your b-day (about 4 months ago...)." So we got everything together and headed out to the storage shed.
Now, one might ask, why would go out to the storage shed when your truck is in the garage. Well... because I have a dismantled SWB in storage and we used the floor to make for a sure fit.
Here's a few pics of the progress and the final result (sorry there not the greatest):
After we ensure the liner was straight, it was time to use a silver sharpie to make the lines for the cuts, and then make the final cut. After trimming the excess off and around the fender wells, we brought the liner back to the house to cut out the stake pockets. All in all, the liner turned out great, and will help protect the floor when we fill in up in two weeks.
