You may want to hookup a pressure tester to the cooling system and put it under say 15 lbs pressure.You can then crawl under the truck and see where the leak is coming from...

so far no white smoke out tail pipe no anti-freeze in the oil.......it's near the top of the rear of the engine......

Possibly the lower intake manifold...
How bad of a leak, just some drops, or a stream?

a stream i can drive it about 10 miles before i have to refill but right now not taking any chances driving it at all

Not saying this is what's wrong with yours, but here's a link to my thread when I had a leak. On the second page there's a picture of the stream to show how bad it was.

thanks everyone found out by a mechanic it's the lower intake manifold gasket at the rear of the engine....he's gonna do it for me for $250.00 that's parts and labor....he runs his garage and he's doing mine cheap on his own time....

For a lower intake that's not a bad price to have it done. Good luck with your rig!
