IMO it may even be better. As noted people have said I got terrible mileage when towing but it is better than everything else I have driven.

You will continue to enjoy the vehicle.....

I haven't tried the air suspension "pick up" but it is such an awesome idea...

As for the diesel, yes I am familiar. My ML320 was only 210 horse and 400 foot pounds and it pulled like nothing was there. The Jeep has better fuel economy numbers AND is more powerful than my old ML so, just dying to get behind the wheel.

Willx, thanks again for your efforts,write-up, and taking the time to answer questions! I will check with my RV dealer to try and arrange a test tow when the time comes. The plan is to get the tow vehicle first, put some miles on it to break it in, and then get the new travel trailer. You have convinced me that the JGC is more than capable and I too am dying to get behind the wheel of a CRD JGC (or maybe RAM)!

At least it will (may) be a little easier for me to wait for the CRDs because I'm a federal employee and I'm getting furloughed 20% of my time from now until October so there would be no way I could pull the trigger until I'm back to full time! Oh the joys...(ill end now before I digress any further).

Re: 2014 JGC Towing Review w/Pictures and Stats

Small Update...

Since I had a few people comment on the mileage, I decided to do the same test again on the return trip. This time around I reduced my speeds by a few mph and was just generally a little more relaxed driving. I didn't really drop below the speed limit much unless it was a really steep hill, so no I didn't drive granny style. This is just to show that a little lighter foot can get you a lot back and you can still drive your age bracket.

Better than a 15% increase in towing fuel economy from my first run (original run was 8.6MPG).

First picture, run out without trailer.

Second Picture trip back with trailer.

To save people looking up the specs, trailer weighs 7200 loaded but it was probably around 6850 on the way back (less beer, food, water). This does not account for any fuel savings. I did a bunch of testing last year towing without water etc and filling on site. I couldn't find any real difference but driving style certainly does change it!!

Re: 2014 JGC Towing Review w/Pictures and Stats

Great write up. I wanted to comment and say the Jeep engineers must have changed the load leveling suspension from the earlier models as my 2011 GC behaves differently. Sitting in idle and in park, when I drop the trailer tongue on to my receiver ball the rear end squats. Immediately the air suspension begins to raise the rear the vehicle. Then when I clamp up the load distribution bars shifting some of the trailer weight to the front, the rear end is up too high. Immediately the leveling suspension begins to lower it back down. All of this occurs when the vehicle is in park but running.

Also with my 4200lb trailer I average 9.1mpg therefore I'm not surprised by your 8.6 with a heavier trailer.

you should see my later post, I was able to easily adjust my acceleration and get 10MPG and still move at a good pace in the hills.

I was completely surprised at the air suspension response. I think it added a tiny bit of air at idle but it sat for 5 minutes and didn't make any big adjustments until I moved it which was very smart.

Re: 2014 JGC Towing Review w/Pictures and Stats

Willx did you notice any sort of pushing or body roll around long corners, I have a cargo trailer, 14ft with a V nose maybe 1600lb loaded and if feels like the back of the jeep is getting rocked in the corners it not constant, 2 of my friends noticed it also on a trip from Vermont the South Carolina. I'm looking at buying a 25-29ft camper and this has me a little concerned

Nothing like at at all. Are you using a sway control system? At 14 feet and a little bit higher speeds you could get some stronger sway. It would feel like the rear corners being tugged.

Re: 2014 JGC Towing Review w/Pictures and Stats

This may be a stupid question, but is the jeep smart enough to drop out of automatic Eco mode when it detects a trailer is plugged in or do you have to remember to turn it off if you stop/restart?

Re: 2014 JGC Towing Review w/Pictures and Stats

Not a stupid question at all, I actually never even thought about it nor did I pay any attention. I am fairly sure that ECO stayed on but certainly it shifted and drove properly with the trailer on. So I can only guess that on downhill grades and coasting that the WDS would come on to save you that little bit. I will need to look at that next time I hook up.... Frankly I never really pay any attention to ECO ever and it has never caused me grief, as when I wanted performance I simply put it in sport (which I was also able to do with the trailer on not that I needed to use it that way).

Re: 2014 JGC Towing Review w/Pictures and Stats

Thanks for the reply. I would have thought you shut off Eco for sure... maybe there is a eco shifting strategy when towing for these fancy new 8 speeds.

I need to grab my tiny little pop-up this weekend, will see if the eco stays on.

Re: 2014 JGC Towing Review w/Pictures and Stats

My Mercedes was the same way, it shifted in what ever way was required, no tow modes on them either. The way I figure it, why not run in V4 mode when coasting to a stop, every bit helps.
