Couple of questions because I am seriously interested in a Ram 2500 as an expo vehicle. What kind of mileage do you get with your mods? How do you like it as an off road vehicle? Does the length/ width ever impede?
The Power Wagon isn't known for it's economy. It's built for hard use, and will hold up to it. The 383 HP and 404 Ft/Lbs of torque comes with a price - I average 11.8 to 12.3 MPG in town, 13+ MPG on the road, and 8 to 10 MPG when aired down. I knew that going into it, and have no regrets about it. My modified Tacoma was getting 15 to 16 MPG, so I'm not loosing that much. Considering the PW carries 34 gallons of gas vs 16 for the Taco, I have much better range even at the lower MPG.
Going to 35's from the stock 33's showed no change in MPG. I had actually expected to gain a bit considering I effectively changed from 4.56 gears to about a 4.30 gear ratio. I suspect the much heavier and more aggresive MT/R Kevilars ate up the difference. BajaXplorer is getting about 1.5 MPG better mileage than I do on 35" BFG A/T's.
I'm very pleased with the agility of the Power Wagon. So far it's gone everywhere I want it to, but I'll admit the truck isn't as pretty as it once was. I live in brush country, and have already pin stripped the truck pretty badly. Some folks just can't stand to do that - but I bought it to use it. The truck has a great turning radius for a 140" wheelbase - in fact, I think it will turn about the same as my old Taco extended cab.
The big truck does things that I struggled with in the Taco. I played around in a gravel pit last weekend that the Taco needed low range and a locker to climb the steepest part of the hill. The PW did it in 4 hi with no problem. On the other hand, some tight sections of trails require much more attention to navigate it thru. The long wheel base also makes most parts of the harder stuff I do feel much smoother, and for a 3/4T, the ride is pretty good on dirt roads and trails.
The new '10 2500 models are going to be longer by 10". That will change the dynamics some. Hope to get the chance to test one late this year!
