Ok, I have a few suggestions for you. Basically, and full-size truck (aka Ram, F-150) are going to get almost the same mpg. My father has an 03 Hemi QC 4x4 Ram. He loves it. Never had a problem, and it has LOTS of power. I would also recommend the Nissan Titan. They have had some reliability issues as of late, but they seem to be fixed. Plenty of power and room with those too. One truck I do not recommend is the Toyota Tundra. It is underpowered, doesn't get very good mileage, and a Dodge Dakota tows more than it. I have a friend with an 05' Dakota QC 4x4 V6, and it is pretty nice, except for the power. You need to get the V8. They are actually capable of pretty good mileage.
