I guess I haven't mention that I'm not just doing this as a favor.
He'd seen my trailer, and called one night asking if he could "hire" me. There is some modest compensation involved, and I have a fun project going.
I'm only logging the time when I'm actually, physically working on the trailer. Not time spent planning, tracking down and acquiring parts and material, etc.
(It's fun, spending someone else's money!)
After about 100 trips to Lowes and Home Depot, I think a tank of gas might be fair.
He's a good guy. We worked together off and on for almost 30 years. I built stuff, and he put the finish on it. We both gave up on the company we were working for on the same day last year. He went on to another job, and I retired.
Anyway...
My back started acting up about the time the PVC flooring showed up. So I put that aside and started working on the ceiling. I've screwed 1x3s to the steel to fasten the panels to, and create a space for a second layer of insulation board. The 1/4" ply is cut to fit and ready for him to finish.
I guess it's time to get down on my poor old knees and get that floor done.
