I did pick up some mirror extensions (Aero 3) and agree they make a big difference! Might look into adding a backup camera to the camper down the road.
Speed.... I have had My truck and 6000 lbs up pretty quick. 90 MPH I would guess.... I haven't had any issues towing thus far. Only issue I have had is getting caught in truck ruts going up hills. You do get pushed around a bit that's forsure.

Re: Towing 20+ foot travel trailer - feedback?

Just a standard ball hitch. No sway bars ect.... been towing for 3 years now for thousands of ks..... there are times though that I would be doing well under the speed limit just depends on the road. You get caught in a groove with a trailer weighing more than your tow vehicle and don't know the road or someone pulls in front of you. It's game over. Have been fairly quick pulling just to get speed for upcoming hill ect.... towing with a truck that has an undersized intercooler and is supercharged your AIT get high really quick. All fixed now but had to do allot of questionable speeds tile towing through mountains to enrue my rig wouldn't over heat. No issues now and proper intercooler installed.

Re: Towing 20+ foot travel trailer - feedback?

Pulling a boat trailer is nothing like pulling a travel trailer. Don't compare the two. I pull both. A boat trailer's aerodynamics are completely different. I don't know of anyone who uses anything other than a bare ball for towing a boat because you just don't need to. Sway is unheard of with a boat trailer.

A travel trailer, on the other hand, is as someone said in an earlier post, a giant sail behind your tow vehicle. The weight is distributed differently than a boat trailer, also. Both factors make sway a very real issue.

I tow a 6,000+ lb 25 foot Airstream with my 2015 JGC EcoDiesel. I use a ProPride hitch, and towing is a pleasure. You don't need to spend $2,500 - $3,000 on a Hensley design hitch like the ProPride, but you do need a good weight distribution hitch with sway control. Don't rely on the Jeep's built-in sway control programming. By the time the Jeep's systems detect sway, you could be in the ditch. You want to make sure sway doesn't get a chance to even start.

Don't cheap out, or think "it won't happen to me." Prevent problems and you will enjoy towing your trailer.

How is your gas mileage and do you do anything for the rear low pressure drag? I pull a heavy ski boat and an enclosed trailer. My gas mileage with my enclosed trailer is a lot less, even when empty, due to the rear low pressure drag. This is at highway speeds btw. I have the Overland CRD with tow package. At the speed limit of 70mph, I'm only getting about 16mpg average on 600 mile trip. No trailer I get about 33 mpg. My boat on same trip I get around 22.

Re: Towing 20+ foot travel trailer - feedback?

Wondering if someone here can help me out with something related to towing. The tire placard on my 2012 V8 Overland says the maximum payload for passengers and cargo is 1050lbs. However, the GVWR is 6800lbs and curb weight is roughly 5200lbs, leading to a calculated payload capacity of 1600lbs. When looking at the specification sheets from wk2jeeps they actually call that ~1600(1590 to be exact) out as payload capacity.

Almost everything in the manual for the Jeep appears to reference either GVWR or GAWR for loading conditions, with the exception of one note under the towing capabilities chart saying to include hitch weight in the number on the tire placard which appears to get silly fast and contradicts the GVWR guidance and calculations.

So I guess I am looking for guidance as to which number is appropriate and rational behind the lower numbers. I saw another post saying that it actually comes from a flow down of maximum GCWR assuming you are towing the heaviest trailer and a "middle of the road" 4850 curb weight for the vehicle, so you get 13,100-7200-4850 or 1050. Is that actually the case?

Interestingly, the specification payload for the 2013 version is 1163 (~400lbs less), even though the curb weight was only 50lbs heavier. Even more confused :X

I haven't towed the boat more than a couple miles on local streets since I bought the WK2 last fall, so I can't give you fuel economy numbers on that. I was getting about 12-13 with my '05 WK Hemi. I tow my 25' Airstream with the WK2 and get about 16-17 mpg, vs 31ish highway with no trailer behind. I tow at ~60, rarely faster.

Re: Towing 20+ foot travel trailer - feedback?

Pulling a 29’ Forest River Surveyor Select behind my 2014 Hemi Limited. It is an ultralight at only 4300lbs dry weight and uses torsion springs, so it sits a little bit lower to the ground than most campers. I am using an Equal-i-zer hitch setup that does have the solid friction bars on each side.

I get concerned looks and questions all the time from people that can't believe I am pulling this big of a camper with a Grand Cherokee.

I really don’t have too much trouble pulling this camper at all. On a non-windy day, I can cruise down interstate at 75mph no problem. There are certain sections of road where the short wheelbase of the Jeep combined with the camper does cause some undulating movement up and down. Speeding up or slowing down usually fixes this.

Windy days can be another story though, and do take a little bit of experience to get used to. My advice – slow down and be careful not to overcorrect when the wind pushes you over a little bit. Overcorrection can get you into trouble pretty fast!!

Overall, love the flexibility of using my Grand Cherokee to pull my camper, but wouldn’t recommend going any bigger or much heavier than my setup – otherwise, get a truck.

Is that actually the case?
For what it's worth, I discussed this with the service department folks at my local Jeep dealer and they agreed that the 6800 GVWR is what should be the guide when looking at total weight of the vehicle, passengers, cargo and trailer tongue weight and didn't understand why the one reference note said to include tongue weight in the lower tire placard value. They thought perhaps it was to cover against if someone put lower rated tires on the vehicle. They also didn't seem to think I would have any issues at all pulling a roughly 5k trailer with my rig. This guidance is consistent with page 542 of the manual that states total weight must be distributed such that GVWR, GTW, GAWR and Trailer Tongue rating / values are not exceed (no mention of tire placard values).

I actually found a CAT scale about 30min away from my house and took a trip out there. My 2012 V8 Overland with tow package clocked in at 5280lbs with a full gas tank but without me in it so very close to the 5210 online specification. As far as I am concerned, this means my effective total payload capacity (which would include passengers, cargo, and trailer tongue weight) is 1520lbs, meaning even at max tongue weight I would still have 800lbs left over for the hitch, people, cargo, dogs etc provided of course everything is properly distributed. Therefore, my tire placard value can be ignored given this measured information and the load rating of my tires (107). Please let me know if I am missing anything!

I have a couple of friends in NJ that would argue with you about that.

They shut down the Garden State Parkway a couple of years ago for two hours when a 22' boat they were towing played "tail wag the dog" to their suburban.They made the front page of the Newark Star Ledger the next morning.

Re: Towing 20+ foot travel trailer - feedback?

I have a 2015 Overland with the Eco Diesel. Love this jeep as it's a towing machine. I've posted in many of the other towing discussions on my experience but here it is again.
Like others have stated, this Jeep is a very capable towing machine. If you have the air suspension you'll want to set up the WDH and sway bars while on level ground with the air suspension disabled. This will help set up you load properly. When the air suspension kicks in it will pick up any little slack that's left. As stated you will want a WDH and sway bar.
I used to own a 2015 Jayco JayFlight 28BHS, 28ft box but 31ft from hitch to bumper. Dry weight of 5500lbs with max weight of 7400lbs. I sold the trailer earlier this spring as I'm active duty military and leave for my new assignment overseas next week. My 31ft trailer won't work on the roads in Europe and the government wont ship it for me. Anyway back on topic, I towed my trailer from Utah to Mt. Rushmore summer of 15 and my Jeep did fantastic. I got 13.2 MPG round trip for 2000 miles. That includes going over passes and with wind through Wyoming and South Dakota.
I will also state that I have a CDL and have driven large trucks and trailers before. If this is the first time you've done real towing just be extra cautious. You can always go slower or plan extra time to wait out weather. Also remember that in most cases travel trailer tires aren't meant to go faster than about 60-65. Look at their sidewall and see their speed ratings. Here's the setup I used to have. Hope this info helps.
