Welcome to the forum.
A good deal is a relative to each individual. For a person with a lot of disposable income, a good deal is different than a person with relatively no disposable income. So the only one who can make the decision on what defines a good deal is you.
It cracks me up that whenever I purchase a new item, (vehicle, TV...) everybody in my family (in-laws too) always asks what we paid for it. I always tell them, we got a good deal. Obviously we got a deal we are happy with or we wouldn't have bought the item.
You can look up the retail value of the Jeep you're looking to buy. Remember though; more modifications usually means driven harder. You know your truck better than anybody else; we have no idea what "rough shape" means.
If you are happy with the amount you pay / trade & what you receive is acceptable to you; then you made a good deal! But don't expect Howie to come out and shake your hand to congratulate you though.
