So I cut the 2x4s for the bed support frame to length, but ran into problems when the only table saw blades I had were 72 teeth or greater. Suffice to say, those did not work very well for ripping the 60.5" boards, but I did all of the shorter ones. I hit Home Depot for a 24 tooth ripping blade, but by the time I was back, it was too dark to work in the driveway so I had to call it a night. My brother's coming over tomorrow to help with ripping the boards down, I'm not sure what else I can "Oh just one more thing!" into getting his help with.
And I swear I'm going to fix the big missed spot on the trailer rail the next time I have the tire off.
