Hi Everyone. I'm new to this forum however not new to Jeeps. I'm a proud owner of a 04 WJ Limited w/ Quadra-Drive I. It has been amazing to say the least.

I'm considering a 14 WK2 Diesel Overland and I have a few questions. So I figured I would ask the experts.

1) What is the reality of the 4x4 MPG? US MPG is 21/28 however Canada/Europe rates it much higher. What are you seeing in reality here in the US.

2) Are there any reliability issues that are specific/unique to the diesel option?

3) I do a lot of towing in the summer. I tow single axel enclosed race trailer. The 04 WJ does fine. Will I see a big difference with the WK2 diesel?

4) What is the difference between the Overland and Summit? I'm happy to spend the money, I just don't know what I get for it.

5) Are there any resale issues vs. the V8? Or do the diesel and V8 hold their value the same?

1) I've had mine for 8,000 miles now. I get around 22 MPG in the city and up to 28 on the highway.
2) It was was back in the shop for twelve days only two days after I bought it. It took the boys in Detroit that long to figure out it was the transmission module. However, it has been flawless ever since. I would REALLY recommend the extended warranty considering the electronics involved.
3-5) The Overland had the bells and whistles and off-road stuff I wanted with the diesel. Love it. Re-sale? If it does what I want, that won't happen.

I can really only answer questions 1 and 2, but I'll give you my experience.

I have a 2014 GC Limited 4x4, purchased July 2014. Right now I have about 22,500 miles on it. I have had a couple of warranty items replaced, but neither were related at all to the diesel engine. (One was front wheel bearings, and the other was a blend door gear in the HVAC system).

I typically get around 25 mpg in mixed driving (mostly in town). On the highway on extended road trips, I can easily get 31 and usually better than that. (My record is 35 mpg from Denver to Des Moines - 750 miles on the tank).

Make sure that if you get a 2014, you have the dealership install all of the software updates. There are several. One dealership here in Denver told me my Jeep was current on software when I knew it wasn't, and another one told me there were 4 updates to install 2 weeks later and there were definite, noticeable changes after the updates. If you test drive it and feel hard downshifts between 3-2 and 2-1 as you come to a stop, there's definitely a software update that fixes that.

Good luck! I love mine!
