I did, and you'd need to have the ignition on at the very least.
The EVIC comes up with a confirmation message.
The handbook warns QL should be disabled when jacking as well so as to avoid unexpected vehicle movement.
It could do severe damage to a finger, hand or head!!

Ok, that's cool. I was hoping that the field of view for the camera would extend down enough for it to be useful for lining up.... but I didn't think of using QL to latch in.... Thanks, even more to make it harder to wait

It is interesting you say this. I am not disagreeing with the manual but when I tested a 2014 summit and it did not load level while hooking up the trailer OR while idling for about 10 minutes. It leveled immediately on driving. It wasn't idle speed either as I was originally a little concerned about it but it worked in a very safe and manageable way.

Anyway thread and pics: 2014 JGC Towing Review w/Pictures and Stats

I know it does not all apply in OZ but I can't imagine QL works completely different there?

I have ordered the Diesel for myself, I was able to get better mileage on my route back but I know what the diesel can do and the HEMI can't compare!

Ours will definitely move to adjust itself whether the engine is running or not.
It actually is a bit disconcerting to sometimes be working beside the thing parked in the garage when the compressor starts and you see a little twitch at either end.....maybe there is a software difference from the 2012 - certainly would make it a bit (edit: a LOT) safer - but sometimes not as pretty in the carpark!
The diesel is becoming very popular here as a tow vehicle, and you won't be disappointed. The eco diesel in the 2014 even has a bit more hp and torque as a bonus.
Thanks for the review link as well, your towing experiences match ours - it is a pleasure to have anything attached to the back, and we've clocked up over 19,000 miles with a bit under 5,000 lbs behind, on all sorts of road surfaces. Your point about the QL lowering at over 100kph (for us) and tightening a WDH hitch (if one is fitted) is spot on as well. You didn't mention about headwinds - that's because you didn't notice any - right?? and you won't.....
John

Head and cross winds are almost not even noticeable. I also think there are some changes in the software to the 2014 (that was tested) I made a note in my review that I thought it very intelligent that it not adjust until it moved.

Thx!!

There does not seem to be anyway to disable the aero mode. This mode lowers the vehicle which obviously will affect the level riders whilst towing

I found it did so in a good way. It increased the pressure ever so slightly for the higher speeds.

Aero mode lowers the car 13mm. I can pretty much guarantee that you won't even notice any difference in the towing characteristics in either NRH or Aero mode. I certainly can't when my 2.5T van is on the back.

Re: The Towing thread

Bugger me! I didn't know this towing thread existed so I've putting towing stuff on another site. I know John and Allypally post there also. So I guess I'll put my latest offerings here as well.

A while back I took the Jeep over a weighbridge. With two on board, Offroad Adventure Pack, rock rails, tow bar, tool box, recovery gear and a full tank, it weighed 1,420kg front and 1,300kg rear. The manual stipulates Gross Axle Weight Ratings of 1,452kg front and 1,687kg rear so no problem. I'm getting close in the front so a future bull bar might be an issue. Anyway, on a recent trip with our Kimberley Camper I noticed the rear car tyres were a little warmer than the rest so when I got back I put the car with trailer attached over the weighbridge. With full everything and gear, it came in at 1,280kg front, 1,720kg rear and 1,180kg trailer. The front was lighter but the rear axle was actually overloaded by 33kg. OK it's not a lot but I was shocked that the axle was overloaded at all. The ball weight of my trailer I measured at 216kg. The tow bar is rated for a ball weight of 350kg which gives the impression that I was miles safe but it wasn't so. The take-away here for me is that back of a bus ticket calcs are fine for a starting point but ultimately one needs to take the rig over a weigh bridge to really know what's going on. In future I'll try to move as much heavy gear from the back of the Jeep to the back of the trailer.

Re: The Towing thread

I've seen a couple of variants of bathroom scales ball weight measuring jigs on other sites so I tried my variation of the theme, see the pic. The issue is that bathroom scales usually max out about 150-200kg but ball weights can go tp 350kg at least for the Jeep. So a jig that would allow the bathroom scales to be leveraged up by a factor of say 3 would be good. I made it out of 90mm stormwater piping. I paid $35 for parts. It needed one 20mm drill hole in the top for the Treg pin and two saw cuts for the tubes plus some gluing of joints. I had some pressure pack foam left over and filled the tubes for added stiffness. The horizontal part is about 300 long with the vertical part exactly a third of the way along so the reading on the bathroom scales needs to be multiplied by 3 to get the ball weight.

Re: The Towing thread

Well worth the exercise Bob, and an excellent example of how to get a ball weight.
Most won't care (or understand) about loadings - and remain in blissful ignorance.
Setting up your combination correctly gives you and the rig the best possible chance should circumstances turn nasty for whatever reason.
Personally i find it scary to see some of the combinations travelling our roads.
