My Ram needs new shocks, help?

Sweet! I'll do a little homework / bargain shopping. I have 3 major expenses and one major decision going on with the truck right now. #1) It needs tires (BAD!). It has had the stock Goodyear AT/S 275/70/R17's since I bought it. I am favoring a Michelin in the same size because they make a better riding / longer lasting tire in my experience. #2) Shocks! (The original reason for this post.) #3) My exhaust pipes fell off the other day. But a friend of mine is a Pypes Dealer and promises me a system installed @ dealer cost.

The major decision? My cousin can get me any Chevy truck I want at $200 over dealer cost. What to do? What to do? I love my Ram, but a new truck for that $$$ is pretty tempting.
