Towing with a lifted truck.

It will kill some of your power because now your truck has to not only tow a trailer, but has to turn the bigger wheels you most certainly have on it. I think you can fix that by changing the gear ratio in the axles..but that's more money.. not to mention the more you lift, the less stable the vehicle becomes (top heavy).

Also those newer dodges get crummy mileage as is (supposedly until they "break in" at 40,000ish k miles)..

Everyone I know who owns one (diesels), regrets getting these trucks because instead of getting 18 to upwards of 20 pulling a trailer with a model just a few years older, these new cummins are getting a whopping 13 highway/empty.. why you would willingly make that worse is beyond me:)

I have an 06 cummins, that I put just and inch taller tires on, and that has had a profound effect on my fuel mileage:( went from getting 18mpg to 14/15 pulling a trailer..

I haven't found any power loss, in fact I found more pull power if anything. Someone else must've thought so too, it was stolen last weekend!

O.O ur truck was stolen wares???? Id be opening a can of whoop-a** right now!

It was recovered, yay!! However the brand spanking new car/equipment trailer attached was not but insurance will replace that. The ignition was punched out, door handle removed & chrome nerf bars stolen. Insurance is more than happy to repair any damages, hopefully it will be ready sometime this week, I hate missing riding lessons! We were out of town at a wedding, took "Shorty" because hubby wanted to buy a new trailer. He left it & the trailer attached in the overflow parking lot of the hotel & caught a ride with my daughter. Later that night when we got back from the wedding party, we drove by the truck because hubby noticed people around it, but it just looked like hotel guests returning, ladies in heels, guys in suits, etc. Hubby said no, he saw another guy near it but that guy was gone when we drove by. Anyways, he thought it ok now & we went in. In the morning it was gone, he was kicking himself for not moving it to the upper lot with cameras! Cops found it two days later, don't really have any other details. Filthy thieves!!!

shouldnt notice much power loss, if so, tuning can make up for it. If you go with a wider tire and a wheel with a negative offset to kick the tires out a little, it will help with the body roll. Mine handles pretty much like stock.

I get 17 city and a little over 20 on the highway with 35" tires. But I also run a custom tune and methanol injection.

The new cummins can get a lot more power if you delete emissions and get a good tune. Especially now that efi live custom tuning is available for the cummins. Im far from a cummins fan, but I've been pretty impressed with the gains the 6.7's are getting that have come thru the shop I work at

I hope my last post didnt come across wrong! Didnt mean to nit pick on everything you said. Diesels, especially the newer ones (all of them lol) can be great trucks, or nightmares depending on whether or not the owner does their homework on them. Everything you said is common belief, and can be true depending on whether or not the truck is treated/maintained right

Another big thing for others looking to lift their trucks, any more than a few inches can really screw up the drive line.

When you start going too high it kills the universal joints on the drive shaft, and the added weight of pulling can speed up the process.

At one time in Alberta lifted trucks were considered not street legal. My nephew had to tow his to an area designated for these trucks.

Thanks y'all but sadly don't have the monster Dodge anymore.. It was totaled out.. I got 17 with a fully loaded hay trailer an around 20 empty on highways..The whole stop an go thing in the city is where your fuel mileage hits bottom I noticed... I got around 15 around town then once I hit the interstate it'd start to pick back up in mileage... Also the tires didn't seem to change anything power wise.
