A testament to Jeep

Longtime lurker, infrequent poster here.

I bought my Liberty CRD Sport new in July 2006:


I have slowly built it into what it is today:



What you can see is a 2.5" lift, Firestone Destination A/T's (LT 245/75/16), Detours USA winch mount with an XRC8 winch. What you don't see is a set of Rocky Road Outfitters Upper Control Arms, Air Lift 1000 helper springs, Hayden 678 transmission cooler, Magnaflow 2.5" exhaust, and a DIY custom tune. The little tractor that could, well, did.

I have a large family - 3 children and a stepson to be exact. I also have a camper that can fit all of us - a 2005 Jayco Jay Feather 29Y bunkhouse. It is an ultra-lightweight (4950 dry and scales at 55-5800 fully loaded for me; I do not travel with water). Some of you can see where this is headed.

This past week, my family and I decided to take a trip to Myrtle Beach to enjoy a long weekend in the sun. Knowing that the family would hate 8+ hours in our Tahoe doing 60-65 the entire way, I decided (perhaps against good judgement) to use the CRD to haul our camper to the beach. My wife, the wonderful person she is, took all the children with her in our Honda Odyssey and followed a couple hours after I left.

We live in Tennessee; east Tennessee to be exact... the part known for its hills and mountains. I knew it would be a challenge, to say the least. To prepare for the trip, I changed out pads and rotors for a set of new PowerStop ceramic pads and extreme duty rotors. Coupled with the Tekonsha Voyager brake controller I have wired up, I had no qualms about stopping the combination.



Now, the length of the trailer is what causes most people pause. Yes, I know that I am a couple hundred pounds over the factory towing capacity. But, if you use the factory GCWR (10,100), I am within the rated specs. Curiously, the factory rates the GCWR as 10,100 with a curb weight of 4300 lbs, give or take, for the CRD. That would actually place the rated towing capacity at 5800 lbs... hmm.... Also, as we all know, Europe got the same CRD, re-badged as the Cherokee, and got a 7400 lb tow rating. Double hmm....

I set up my spring bars, adjusted the sway control, added 15 lbs to the air lift springs and set out on the road. Within a couple miles, it was clear: This combination towed way better than I expected. To the lady in the Suburban who helped me perform an emergency braking test: Thanks, but get your head checked. Remember the braking I described above? It works.

Once out on I-26 and in the open, I set my sights on 62 mph and let the truck eat. The Jeep had no problem maintaining speed, loping along at a lazy 1900 rpms and 62-63 mph in 4th (O/D). Most hills weren't a problem, and O/D would hold down to 52 mph. By that point, I crested most of the smaller hills, and I simply downshifted from O/D to direct (3rd) lockup to climb the larger hills. I had to be careful to keep speed below 65, or the transmission would shift into 5th (double O/D). It would still maintain speed, but I would get some bad converter shudder while climbing even the slightest hill.

The torture test came in the form of Sam's Gap and Buckner Gap. As I climbed east coming from Unicoi County, TN, the winding portion of I-26 climbs a 6-7% grade up to 3,370 ft over about 4-5 miles. Fortunately, I was blessed with cool temperatures (60's) and light traffic. I set the Jeep at 70 at the base of the mountain and climbed in 3rd (direct) lockup for most of the way. At the 3/4 mark, I had dropped to 50 mph, and the temperature gauge was starting to climb. Although it hit the 3/4 mark on the gauge, I never got a warning light (234*), and the fuel curve was never pulled back (225*). That indicated to me that coolant temperature never hit the 230 mark. To be on the safe side, I turned the heater on high, dropped the windows and downshifted to second. Transmission temperatures stayed below 210-215, thanks to the large Hayden cooler that I have in series with the factory in-radiator heat exchanger. I'm sure the large obstruction in the form of a winch, solenoid box and two driving lights didn't help with radiator air flow. Since getting home, I have thought about rigging a manual switch in parallel for the pusher electric fan so that I can turn it on separate of the A/C.



At the crest of the hill, all was well, and I was on to Myrtle Beach! The gauge never rose again, and there were no signs that any damage had occurred as a result of the rising coolant temperatures. In fact, while descending the other side of the grade, I cut the A/C on high to try to get heat back into the cooling stack, as the temperature gauge rapidly plummeted! When I reached the bottom of the grade, coasting in O/D had caused the engine temperature gauge to drop to the 3/8 position!

Edit to add: Once out of 2nd/unlocked T/C, the transmission went back to lockup and temperatures dropped and remained around the 170-180 mark.



The rest of the trip was remarkably uneventful. The Jeep pulled smooth and steady the entire trip, and the combination was limited by tire speed (ST 205's on the trailer speed limited to 65 mph), although I doubt I would want to travel much faster than about 65.





This is what it's all about (my girls chose the awning LED colors this night):


Did I mention the combination averaged a hand-calculated 15.3 MPG? :shock: That's better than my Tahoe usually does unloaded! And that was with the A/C running for most of the way (save cresting the gap).

The tires never got more than slightly warm to the touch each time I stopped, and bearings stayed at or near ambient temperatures. The trailer brakes are relatively new, and stop well.

FLEA, I used to haul a 17' hybrid with my Jeep Wrangler with the inline 6, had a tow rating of 5,000. I did use a w/d with it since it was much longer than the Jeep. It did great, even at Sam's Gap and coming home up the Green River Gorge.

On a side note, check out the Volunteer Campers Club, out of East TN. Having our semi-annual camping trip here in a couple of weeks. We are on the net and also on facebook. Most of us have kids, dogs and campers so you would fit with us. We are located all over E TN and SW VA, but most in Johnson City, Kingsport, Gray, Bristol, and over into the Knoxville area.


No jeep wrangler has a 5000 lbs tow capacity. 2000 for the short tjs and 3500 for the long wheel base tj or jk unlimiteds.

Factory payload is 1100 lbs rated, with 1400 lbs of available weight carrying on the axles (going by combined front and rear GAWR). Factory horsepower is 163, 295 torque. I am at 190 and 330, respectively.

I am curious what the max cargo capacity of the Jeep was from the factory? Also the horse power?

Sound like you made a good TV.

FleaM35A2,

I bought a new Liberty CRD Limited in 2006, too. It's been an awesome vehicle for 9 years so far. We have over 175K miles on it and still handles & drives like new. I got the limited version with all the bells and whistles on it knowing that we were gonna hold on to this one a looooong time and wanted all the creature comforts.

The thing is great in our northern snow, too.

To answer some questions, I took the Jeep because I figured it would do nearly double the mileage when I was working up the tune. My suspicions were correct; the Tahoe usually averages about 8-10 while towing. I spent about $120 on gas for the Jeep for the entire trip -- exactly 3 tanks in total. Unladen, the CRD gets near 30 mpg with the tune.

The Jeep, despite its apparent size, is on par with a ZJ Grand Cherokee in terms of dimensions, and it has stronger axles, better brakes, and a better transmission.

I had no qualms about towing heavy with the vehicle. I have towed at the factory limit many times, but always with brakes on the trailers, and always at reasonable speeds. The Jeep has never felt over worked with anything I have used it for.

The Jeep handles very well, and the wheels I have on it have increased the track width by about 4-5 inches. The tires are also much wider than the factory offerings, with stiff sidewalls and a high load rating. Sure, aired up they don't ride as nice as the butter-ply factory Wrangler SR-A's, but the increased footprint added a great deal of stability. I never once felt the tail was wagging the dog, but I packed smart and secured anything that could shift. I never felt the pushing sensation from big trucks, even when going in the opposite direction.

I had power to pass when I needed it, and decent fuel mileage when I didn't.

The ABS has roll mitigation built in to it and also functions as traction control.

The main reason though? Because I could. Really, that is about as simple as I can explain it. I certainly wouldn't use the Jeep for a standard-height trailer, nor would I feel comfortable with a heavier unit. But for the trailer I have, I wouldn't hesitate to leave tomorrow with the same combination bound for anywhere this side of the Rocky Mountains.


I agree , great post .

Great Post. Dont let the Nattering Nabobs of Towing Negativity get to you. Your post gives the lie to those that insist you must have a 3/4 ton to haul anything safely. In my recent trip I saw much more of this kind of vehicle combination than I ever guessed. Some people had towed from New England to AZ. Not only CAN it be done it is being done by many and SAFELY.

As to the differing towing capacities between here and the European model of your Jeep. I have tried to explain many times on this forum that those numbers are an agreement between Engineering and the Corporate Lawyers. There is at least 1 1/2 times safety factor in them and probably more. In Europe they do not have to worry about law suits as they do here. This results in a more realistic towing capacity for the same vehicle.

I used to tow an 18" HTT with my liberty gasser. Towed great. I got 15.2 mpg one one trip but it was mostly level ground. Hard to believe but they do make good tow vehicles. Never had any sway when being passed by trucks or busses.

15 mpg at 60 mph, that is the most impressive part of the story.

If the combo works for you that is all that matters.
