Well I did it. I put boards side by side and stove bolted with 1/4 galvanized bolts 1" from the edges. It took alot of bolts but it was fun and it looks great. I tung oiled it today. It should last as long as I own the truck. It sure will get more oil on it in the future from some stuff I will carry(engines and trannys) I'm sure. I think by not tungue and groving, it will allow the boards to move and flex as needed and allow it to dry in between the boards. It might leak a little sand if I carry a load of it, but thats the least of my worrys. Thanks for all the input on this. Ya'll were very helpfull as usual.
