That's a nice looking rig. I'm working on a F150 but have been seriously thinking of switching to the Ram. My son runs a 2500 and he's in the process of fixing it up an I love the way it looks.
Ram 2500 Power Wagon will give you front and rear lockers from the factory, disconnectable sway bar, and warn winch and 2 inches of lift over a standard 2500 4x4. It's funny, but all the work you have to do to put 35's on a 1500, I can run 37's stock. :pYou'll be puckering up on tight trails with either rig, but the 2500's are a way better overlanding platform in terms of off road performance and upgradability. (It is hard to beat solid axels at both ends). I use my truck for almost everything, so getting the 2500 wasn't worth the sacrifice in fuel economy. I have been very happy with my truck, but there aren't near as many parts available for it as the the F150 you currently have.
That's why I stopped building my 1500 and just upgraded to the Wagon. The 1500 is a lost cause if you want to get serious.
I daily drive mine.
