The Ram 2500s have Coil Springs with Optional Rear Air suspension. The Ford F150s have leafs in the rear.
My coworker has a 2500 with the 6.4, and loves it. He was telling me on the hiway, with cylinder deactivation, it gets decent mileage. Of course, as with all railroaders, it is probably a fish story, and his mileage isn't as good as he claims.
And the Ram with the EcoD, would handle 7000. Especially with the 3.92 gears and Green Diesel tune. But, there are a few model of grills to avoid due to poor air flow. I have one of them, and will be changing my grill inserts. A few of us here are on the
Ram 1500 Diesel Forums. If interested, ask away. And, remember, just like every forum, people go there to post issues.
