I have found that it is very strong for a little v6. It's actually probably faster than my truck. According to google the wrangler with the 3.6L does 0-60 in something like 6.7 seconds. My truck is right at 7 seconds. That pisses me off LOL.
Ahh, that is exactly my point. When my Wrangler was stock, it was as you said above, good mileage and ran like a champ. But, add a 3" lift and agressive tires to the mix and the V6 suffered a whole lot more than I expected, even with the lower gears. Its fuel economy dropped like a rock and highway performance was poor. By poor I don't mean it was bad for a lifted Jeep but considering its power numbers on paper, it was dissapointing. I guess they engineered it to do its job well at a specific configuration but getting outside of that caused a big drop.

So, I wonder if you take the RAM, add a 2" or so leveling kit, a heavy bumper and some agressive tires (assuming they are close to stock height), if the fuel economy takes a big hit and highway speeds suffer.

Sorry to hijack the thread...
