I wanted to get back into a truck, so I started researching different trucks online. I've had 3 Ford's, 2 Chevy's, 2 Jeep's and 1 Nissan Frontier. I'm really a Ford guy, but their gas mileage stinks! Dodge's popped up and I saw that they get better gas mileage than my Grand Cherokee. I've had my '05 1500 for a week now and I love it. I got the Hemi and the gas mileage is actually pretty good. My Dad is a Die-hard Ford guy and just bought a brand new F150 and now wants to trade it in for a Ram because he likes mine so much. I test drove a few 4.7L Ram's and if you really are looking for the best gas mileage out of any trucks, that's the one to get. It's not the same as the Hemi, but it'll go!
Just as roomy as the Ford's and way more roomy than the Chevy's. The performance (speed & handling). The look of the truck.
The only improvement I would suggest is level the front end from the factory.
