Greetings. Post #1 . About to plunk down more money than I've ever spent on a vehicle (by a healthy margin) to get a truck that will probably outlast me. I will get the crew cab and would much prefer the 6'4" box but am unsure if that's an available combo. I want to have a reasonably decked-out truck, but am having trouble getting the lowdown on the Big Horn and Laramie packages; what's included and what's not. From the reading I've done, I know I want the air suspension. I'm a little concerned about reports of a harsh ride on 20" wheels so if someone could tell me their experience with them, that would be helpful. I want to obviously pay as little as possible for this grand acquisition, so am looking for every advantage I can find, including the credit for military personnel (I'm retired USAF). I plan to use USAA's car-buying service if I can, since they proclaim thousands of dollars in savings if I do. Any advice from y'all on strategies and what to watch out for would be appreciated!
