Lots of reviews on the internet about the Diesel version of the Jeep Liberty, but very little in regards to reliability and engine life. 
Would love to hear from greasers what you think about these SUV's.

I have a Liberty CRD, which I am in the proccess of converting to WVO.  There are not many around, and even fewer running VO, but there are some.  I think Elsbett makes a kit, but I have never seen one.
It is a very nice little vehcile, emphasis on little.  There is not a lot of room, for cargo or passengers.  Even less for grease tanks and components.  I wound up making a tank to hang under the vehicle on the driver's side, but it is tight.  Others have converted the diesel tank into a dual tank, and one guy made a very nice round tank to hang where the spare tire goes.
My engine has been pretty much flawless for 50K, though I do see a small oil leak developing now.  Mileage is only okay, never reaching 30 mpg.  It is a heavy vehicle.  Drives very nice for an SUV.
There is a pretty active contingent on the Jeep forum "LostJeeps".

Hi Phil!   I need your advice!   I bought a 2005 liberty CRD on monday. I want to do WVO.  But, I have been told my some people, including a biodiesel "expert" that this will ruin my engine. They say it works on old 1980's merecedes diesel's but not new modern clear diesels.  How long have you had your liberty converted?  How's it running?  Can you tell me some details about your VO tank?  I would like to put it under the vehicle also.  Which greasecar kit did you use?
Thanks

Last September of 2011, the NHTSA had amended it to an engineering analysis, as more complaints of the problem had been logged. Eventually, the problem was traced to road salts, the salts used to de-ice roads in winter conditions. Thus, A recall has been announced for the Jeep Liberty. The model years impacted is for 2004 and 2005, affecting over 200,000 automobiles. The problem is with road salts used in specific states, which can cause the rear lower control arms, an essential part of the steering system, to corrode and break Source for this article: Road salt corrosion leads to Jeep Liberty recall.

Hello DieselKJ,
While my kit is almost completley installed, I have not yet cut the fuel lines or hooked up the coolant.  I am hesitating because it is my wife's vehicle, and I'm not sure she should really be driving a greasecar.  She does not use it much, and mostly for short trips, and would not apppreciate a fuel leak or air in the lines.  
So I really can't answer your question from personal experience.  But from the experiences of others, I believe it will run just about as well as any of the newer diesels, like the VWs or pickups.  Which is to say, it should run very well on WVO.
There is a fellow on the TDIClub forum who has put quite a few WVO miles on his.  He built a small tank underneath which is fed by a larger spare tire tank. It seems to work quite well.  I have seen a few others around, and they seem to work fine.  There are even a few people blending diesel and vegetable oil in the main tank (I'm not recommendng that) and they seem to be succesful.
Greasecar does not sell a kit for these cars so I made my own.   I tried to get Frybrid to make one, but that never happened. I think they are pretty much out of business now.
 I bought the valves from Greasecar, had a custom tank made to fit under the car (about 14 gallons) and installed a Hotfox to heat the tank.  Hoses are HIH, with most fittings coming from McMaster-Carr.  I also got 12 volt heating pads from them to heat the filter.
I don't know where you are, but if you are anywhere near Connecticut, you are welcome to see what I have done with mine.  The guy on the TDI Club is in Florida if you wanted to get in touch with him.
If you don't already know it, the LostJeeps forum is a great source of information and has an alternative fuels section.

My Jeep Liberty is amazing vehicle easy to park good power, space, and an easy grease conversion. I have a 3 tank system. There is a small heated tank behind the drivers side rear tire. And the main fuel tank is mounted where the spare tire was located. Total volume is over 25 gallons.  We converted at 73k miles and it now has 118k miles.  Grease system needs to be flushed every time that the engine is going to be turned off.
I talked to the people at greasecar and they did not want to offer a kit for the Jeep. I built one myself using some of their parts those SV valves are great!  The Jeep like to be tuned just right to run good.

I have a link to the Lost Jeep website that I have lots of pictures and discriptions.  This is the one decribed earlier in this post.  My wife drives my with no problems but her trip is 60 miles each way to work.
