I am building back a 3 ton 51 gmc and the bed needs all new wood. I could go with the standard pine 2x8's or I have some 1" thick cherry. I dont plan on really hauling tons of weight on it, my other truck can do those jobs. Any thoughts ? I appreciate it  Troy | | | | | Joined: Jun 2011 Posts: 1,901 Shop Shark | | Shop Shark Joined: Jun 2011 Posts: 1,901 |

That is good to know, that I can use whatever will work  Also, CASO, that is a great chart there. Thanks for sharing.

It is a Malaysian hardwood , because that is what was available. Oiled up it looks fabulous and is durable enough to see the trucks life out too , I think.  | | | | | Joined: Jun 2012 Posts: 166 'Bolter | | 'Bolter Joined: Jun 2012 Posts: 166 | Thanks Dusty, I agree with your thoughts totally.... I bet the wood in your truck bed looks awesome  | | | | | Joined: Aug 2010 Posts: 775 'Bolter | | 'Bolter Joined: Aug 2010 Posts: 775 | What's the front to back spacing for the supports under the bed? On my 46 there are 4 supports one on each end and two in the middle. If your's is a flat bed and greater spans the thicker material will be better. Try a few pieces on a pair of saw horses placed at the support distance you have and see how it flexes. Fyi Pine is soft wood cheery is harder but not real hard. | | | | | Joined: Jun 2012 Posts: 166 'Bolter | | 'Bolter Joined: Jun 2012 Posts: 166 | There are 10 supports/cross members including the front and back. It has plenty of support back there... Too, I dont plan on hauling too much weight back there as I have another truck for that  Thanks for advice.
