Looking to get into a Ramcharger...

I have owned a 92 Ford Ranger 3L regular cab for almost 18 years now, and while I love that truck and will never get rid of it willingly, I am looking to pick up something a little bigger (I'm 6'4") and with 4wd. I love the old Dodge Ramchargers, and have been doing some research, but I have a few questions. What is the best year(s) to look at, would I be better off with the 318 or the 360, and which is more reliable, automatic or manual? I'm sure there are pros and cons to each, but I would like to hear from those that have actual experience with them. Also, what would be a good price to pay? I've seen decent looking examples of pretty much each decade they were offered going for between $2K and $5k. Any and all advice would be most appreciated. Thank you in advance.

Edit: I posted this over on the Trucks forum, but figured I would post it here too.
