    Technically a rebuild...it had a flatbed that was rusting through pretty badly...I could almost fit my foot through a couple of the holes. Trying to get it done before winter.

    It's a steel bed with 1 5/8" oak as a decking material. Wood looks good, hope it holds up ok. It's red oak, which isn't as good as white oak for outdoor, but I had the logs and had it cut pretty cheap. I got a marine varnish that I hope will help.

    8' 6" long, the old bed was exactly 8', which was very annoying when trying to load plywood or sheetrock, and also get the tailgate on.

    I think that guy might need more help than just a flatbed. Never would have thought to get a running start when loading a trailer :help:

    I grooved out the area where the flat stock joined so I could get decent penetration on the welds.

    When i cut trees, I move the pieces out in log length and cut it and split at my house. Those first pieces can be pretty heavy and roll into the sides hard when they come off the forks on the tractor. The old sides had bent from just being sheet metal-I don't want that to happen anymore, hence why the sides are built so heavy. 3" by 3" 1/4" thick angle with a full weld to 5" by 1/4" flat stock.

    Good build. That last pic looks like a heavy load.

    Got about everything done except for the headache rack. I welded in a couple of posts that i will weld the rack to later on. Spent the day yesterday sandblasting and cleaning it up. Got a coat of primer on it last night.

    Nice, especially since you supplied your own wood. How Many miles on that truck???

    Truck has 178,000. Bought it with 148,000, and been abusing it ever since. Holding up pretty well, and a lot less expensive to run than something brand new. Flatbed with 1000 lbs counterweight and my 8'6" V make pushing snow a lot of fun.

    Looks good. I built a dump bed for my Chevy and used wood like you did. Did not like the wood. The one I built for my Ford, I used diamond plate. The wood shrunk and bucked like crazy,plus I had to drill holes in the crossmembers for the deck screws which I did not like.

    Looking good.

    Boy I should have bought back my 04 that was totaled out here recently and had someone do the same exact thing.

    I'm hoping that using oak will help it hold up a bit better than pine/fir box store wood. I am using red oak, so the jury is out, but I think if I have a problem I can replace with white oak and be ok. I had trex on my old truck bed, which I really liked, but it is not cheap unless you have some extra lying around.

    I will be bolting it down 2 spots per cross-member with carriage bolts, which I think will prevent it from warping.

    The old floor rusted out starting from each crossmember, because of salt trapped between the diamond plate and the structural steel.

    I did not like drilling in the cross members. I allows road chemicals to impinge in the drilled threaded hole. If you look at my build on youtube i show how i tried to prevent the rust from cross members to diamond plate floor. Youtube user name. Tjsnordic

    Got a coat of black paint on. Will do another coat on the outside surfaces come spring, it's getting pretty cold to shoot paint. I have a torpedo heater in the shop, but it's not insulated and very drafty. Took a couple days, but seems to be hardening up ok.

    After 6+ months with the wood, I concur. Even though I installed the wood in the winter, most boards have 1/4"-1/2" of gap now in the summer. I would have expected swelling with the humidity, but it shrunk. No more wood decking for future builds.

    Built another bed for a friend with 3/16" diamond plate, looks real sharp. Will get pics when that bed gets installed. Going on a 2012 3500HD SRW.

    The wood will stop shrinking after about a year or two. I redecked a trailer with green oak and just put them in with no gap and real tight now a couple months latter it has nice gaps in between the boards it worked out great
