I see you're taking Grewe's approach to adding up prices.
First off, you probably dont need a new alt/battery. And you can definately find both for cheap.
A skyjacker 6 inch for 2K? You shouldnt pay that much to lift your truck.
Also, its a 2wd, skip the detroit and just go for looks.
You can pick up tires for as long as 600 shipped for 4 35 inch tires.
For wheels go with cragar soft 8s, 40$ each = 160$ total.
Definately upgrade rar end to 8.8
Don't get a winch bumper, especially for $500.
prices for repair panels are fine, you should see if theres a "certi fit" shop near you, where youc an buy the panels.
Also, for the hood hinges, get em for 10 bucks from a junkyard.
That's any improvements i can think of. Just go for the looks of a lifted truck(and the front end update would be sweet) because 2wd you wont offroad nearly as well as a 4wd. Just go big and lifted and hope the chicks dig it. Plus I know you're near the beach, and you'll get stuck in the sand.
