How fast were you going and how heavy was the trailer/camper?

High 20s is easy, even at 70 plus. I didn't drive slow with the trailer either... certainly people get better than me but your mileage sounds close to what I was getting in my 2010 Yukon so doesn't surprise me.

I kept the speed around 60-65 mph. Most travel trailer tires recommend not going faster than about 65. Here is my current set up:



It's a 2008 Nissan Pathfinder. 5.6L V8 (same motor as titan and armada). I have a K&N intake, Bully Dog programmer, 8Klbs warn winch mounted up front. Will pass anything on the road but a gas station.


2015 Jayco JayFlight 28BHS. Dry weight is about 5200lbs. GVWR is 7200lbs.

This is the information I'm looking for to convince the dear wife of mine that it's time to upgrade to something with better day to day mileage and towing mileage. I still drive my 99 WJ with the 4.7. 4inch rough country with 32inch wrangler wheels and tires and around town I get 16 MPGs.

One thing I would tell your wife... beyond the mileage improvement is the comfort factor. Not just the ride comfort (because I cant compare with your truck I don't know) but the lower rpms, less noise and high pitch vibrations. You can drive a diesel longer distances with less stress on your body. You would not believe the impact of high RPM Gasoline engines on you (until you have done Diesel).

Anyway, my Jeep made me branch out into so much more in the camping world... I now have a 2015 Longhorn Crew with the Cummins (High Output) and a 15.5k GVWR 5th wheel. MY Jeep Diesel was still the most comfortable best preforming package for a trailer your size though IMHO.

Thanks for the additional info to push to the wife. My 99 even with the 4 inch lift still rides nice. It can be rough at times but the unibody just acts differently than my Pathfinder which is a body on frame style SUV.

Re: 2014 JGC Towing Review w/Pictures and Stats

Hi,

We just this past week picked up our 2015 GC Ecodiesel with Quadralift which we are going to use for towing our 22ft Jayco JayFlight 22FB.

We're absolutely new to the Quadralift thing and the various ride modes, auto leveling and etc. so I plead ignorance, however I have set up our previous tow rig which was a '94 Ford F250, so setting the equalizer hitch is not new to me.

I have a Reese equalizer hitch and I'm going to be setting up the ball height, the bars and the weight distribution on the GC with the Quadralift.

I've searched the forum and this thread, and I haven't really found the answers, or I've found somewhat conflicting advice, so I'm hoping someone who has done this task on the GC with Quadralift can give me some much appreciated information.

1. Should the vehicle be in "aero mode" or "NRH mode" when measuring ball height and tow vehicle front and rear leveling measurements?

2. How do I place the vehicle in the proper mode ("aero mode" or "NRH mode") and keep it there while I'm outside the vehicle making the measurements? (Avoiding entry/exit mode, etc.)... Must the engine remain running through the procedure to keep it in the proper mode, how to shift into the proper mode, etc.?

3. After I set up the hitch initially, should I place the vehicle in the same mode that was used for the setup listed above at each instance of hitching/unhitching every time we use the trailer?

4. How do I make sure the vehicle is in the proper mode in travel when testing at the location that I'm doing the setup. I'll be in a parking lot that's mostly level, so there won't be a lot of speed as I move the combination of GC and trailer hitched up while testing the heights, etc.

Please forgive me if these questions have been answered previously in the many threads here. These are probably very obvious ignorant "newbie" questions, but I guess I'm an admitted ignorant "newbie" to the GC Quadralift and I want to do the setup the right way the first time.

Thanks in advance for any help, it's much appreciated.

Bluegrass Picker

Re: 2014 JGC Towing Review w/Pictures and Stats

1. You need to be in tire change mode.
2. Then measure the wheel arch heights, front and rear and note heights and any differential (e.g. 1/2 higher at the front etc).
3. Measure your trailer front and rear using a constant (the frame?)
4. Put trailer on hitch ball.
5. Install WDH so that the front and rear measurements are, as near as dammit) consistent with 2. above. You will have more weight which will probably reflect in lower heights than in 2. above. You need to ensure that you see the same differential (e.g 1/2" higher at the front).
6. Measure your trailer height again, as in 3. above. You want to see it the same or slightly lower on the front.
7. To help with 6. Use a carpenters level on the trailer, using the top of the external fridge outlet. Which is usually square to the frame.
8. Once you have it set up, you THEN put the QL back into normal mode.

All Excellent Advice....

I want to add one thing and that is that after setting up, it was good but I added one of those spacer rings back in to apply a little more pressure forwards (and back). It was more how it felt in a little bit of a cross wind.

The Jeep is VERY good at adjusting accordingly but just make sure it "feels" right going down the road.

Re: 2014 JGC Towing Review w/Pictures and Stats

Barboots,

It really depends on what WDH you are using but I believe Willx was referring to something like the Torklift WDH.

Typical Weight Distribution System

I use an Andersen WDH, which only requires you to tighten up the chains to add additional forward weighting

Andersen 'No-Sway' Weight Distribution Hitch

Thanks for your reply to my post.

I finished (I think) the job today, and here's my results. Perhaps someone here can tell me if I set things up correct or if I should make some changes...

1. The manual doesn't say how to disable QL and how to put it into tire change mode, so I had to research that one out. Press the up and down buttons simultaneously until the DID says that QL is disabled.

I found that I had to make sure the QL was in normal ride height before going into tire change mode, since it could also be in entry/exit mode which is lower.

2. I measured the wheel well height front and back with nothing hitched. 34 3/4 Rear, 33 3/4 Front.

3. From measurements I found that I had about 3 ball heights available to me on the hitch. I hitched the trailer with the lowest height and connected the WD arms.

4. I found that I had to drive the setup around the block to enable normal ride height with QL and let the auto leveling kick in to get real measurements, and then I placed the GC in tire change mode again.

5. Ball height in low position, GC Front 33 1/2 Rear 34 3/4. Trailer Rear 18 Front 17.

6. I moved up to the 2nd ball height, about 1" higher and repeated #4. GC Front 33 1/2 Rear 34 3/4. Trailer Rear 17 1/2 Front 18.

7. I moved up to the 3rd ball height, about 1" higher and repeated #4. GC Front 33 1/4 Rear 34 1/4. Trailer Rear 17 Front 18 1/2.

8. I relocated the ball to the lower position described in #5 thinking that should be the position to keep.

I haven't had a chance to get on the road with the setup, but does the #5 position sound about right to those of you who have done this sort of thing?

Did I do correct by letting the auto leveling and the QL kick in before taking measurements?

Will Aero mode change the setup significantly so that I should plan a different setup to compensate?

Does anyone here have any recommendations or alternatives or suggestions?

(I'm totally open to someone saying that I botched it up and should start over)...

I should mention that this was done with the water tank empty and the trailer and the GC partially loaded, but there are some things that we would put in when we hit the road. Probably nothing of a major weight increase. I'll recheck the measurements after loading just to be sure. (Water tank is over the axles, BW-GW holding tanks are behind).

Last question, how do I make sure that the trailer tires (double axle) are equally balanced in load from front to rear?

Thanks to everyone for the help.

Re: 2014 JGC Towing Review w/Pictures and Stats

You must take ALL measurements with the QL in tire change mode ONLY. You can also put it in Tire Change mode from your Touch Screen.

You need to get that front 1 inch differential as near as dammit and check the trailer for it to be either (near as dammit) level or slightly lower on the front. Once you have that done.....you are done!

AFTER you set up the WDH in TIRE CHANGE MODE ONLY, you put the Jeep back in regular QL and just drive. Don't worry about height adjustments and Aero mode, the QL suspension will do its magic for you.


Your LOW ball position figures in 5 look to be the best !
After all this, you could obtain your tongue weight when loaded (ask if a local dealer has a tongue weight scale available) plus take it to a truck scale and get the distributed weights on all axles. i.e. Front Axle of TV, rear axle of TV and then the weight on your TT axles. That will give you the axle loadings of your TV plus the GVWR of the TV and the GCWR of your set up.
