Dorsey, welcome to the stovebolt. Sounds like a good plan you have going for you. Always think it through. There is a lot to be said for all trucks and conditions. Its just determining what fits for you. I like the idea of one that is pretty decent and will save money in the long run. Unlike me, all I could afford was the basket cases and then spend years trying to get them on the road!!!!
The Navy trucks can be a good buy but they are stripped and I do mean stripped. A friend of mine bought a couple decent ones for 1500 each. The brakes and things are also stripped off but most of that stuff is pretty much available....even from local stores.
Again, to each his own.
Sounds like you got a good lady. Keep her happy and you'll have hours of fun on the truck! Unhappy..... well, you know or you will learn

Keep us posted. This is a great site and nice folks.
