Re: V6 WK2 Towing question

^the first photo looks like a hi rise for short hauls, would not want to pull that sail any distance or speed.

Maybe try this with 5' height, lite aluminum hardsides, and double axle stability (does not appear to have anything beyond surge brakes).

Re: V6 WK2 Towing question

You should not flat tow a GC 4x4. suppose you could a 4x2 if you removed the driveshaft & sealed the diff. but the manual says only with the rear wheels off the gound.

With the engine off, the trans oil pump does not turn and things get dry.

BTW surge brakes are a simple idea that work surprisingly well.

Re: V6 WK2 Towing question

it's actually just the opposite. You can flat tow a 4x4 in P or N with the transfer case in neutral. You can tow a 4x2 with the rear wheels raised off the ground.

Re: V6 WK2 Towing question

Minor quibble: Flat towing of a 4x4 is allowed only if the transfer case has a NEUTRAL position (Quadra-Trac II). Both driveshafts are disengaged so must set the parking brake to hold position since will roll even though the transmission is in PARK). See pp 538-546 in the owner's manual (12WK741-126-AE, 5th edition)

One thing that is confusing is that everything up through the Overland says "Available Quadra-Trac II® 4x4 System" but I do not see it as an option. Do some WK2s get the Quadra-Trac I single speed unit ? YWTK

Re: V6 WK2 Towing question

Yes, some get QTI. Like me, for example.

Re: V6 WK2 Towing question

Think the trailer package also includes electronic anti-sway control that applies individual front brakes to dampen trailer sway...

Re: V6 WK2 Towing question

I bought a 2012 WK2 about 3 weeks ago and am currently about 6 hours into a cross country move due to military orders. I have the V6 4x4 with the trailer tow group package. I rented a 6x12 u-haul trailer and have my vehicle pretty much packed to maximum vehicle specs (I have the weight tickets to prove it haha). So far I have been able to maintain 70 with no problems, the engine has been consistently holding 2500 rpm. I'm only getting about 13 mpg but that is to be expected when hauling this much. I've been keeping an eye on the evic gauges and all seems to be holding steady so far. So far so good, it's all been flat however, I'll let you know how it handles when we get into more hilly country.

Re: V6 WK2 Towing question

I am currently driving a 2002 Ford Explorer Eddie Bauer with the V8 engine. I tow a 3000lb Lund aluminum Fishing Boat with all my gear inside. My Explorer seems to handle this set up with no problem. It does have 134K miles on it and am concerned when I travel out of state to other fishing holes.

I am going to purchase a new GC Overland in the fall and am undecided between the V6 & V8? My question to all you GC towing partners is: Is the V6 capable of handling the set up I have? I know the Hemi is probably overkill as my max. weight towing is 3000 lbs. Can the Pentastar handle my set up without straining the engine and trans?

This is a great forum and would appreciate hearing back from everyone who tows with thier GC.

Thanks and Happy Fishing to all you sportsman fans out there!!!

Re: V6 WK2 Towing question

^kajb, i normally would recommend the Hemi for towing regularly, but an aluminum lund, single-axle trailer, and max tow load of 3k lbs might be fine with the Pentastar so long as you aren't also dealing with hills, muck, and a 4 large passengers in your JGC.

Re: V6 WK2 Towing question

Moosehead,

Thanks for your imput! Being that the Pentastar engine is relatively new, I am concerned about the strain on the engine and trans. My current V8 in my Explorer produces only 240HP and the truck only weighs 4300 lbs. I know the GC with the V6 weighs in at 5000 lbs.

Add in the wieght of 2 people, fishing gear and 30 gallons of fuel in the boat and now were talking about moving a 5500 lb vehicle PLUS towing a 3000 lb boat and trailer? That's a whopping 8500 lbs.?

I probably tow about 12 times a season in the midwest so I don't want to be underpowered?

Keep the comments coming! I really need some real live experiences from our fans out there.

Thanks,

Re: V6 WK2 Towing question

The max gross weight for the V6 Grand Cherokee is 10,400 with a towing capacity of 5000. My Jeep plus trailer is weighing in at 10,300 loaded with my family and all my stuff, towing weight being about 4600. I have currently driven 1600 miles of a 2300 mile cross country move and it has held up just fine including fairly major hills through New Mexico. I had to back off some but according to my GPS my average speed is 67 mph. I wouldn't say it is the best for towing but it is capable if it is not something you do on a regular basis. Obviously I can't speak for the long term but I am very pleased with its ability so far.

Re: V6 WK2 Towing question

It may seem odd but road racing a Corvette teaches you to "drive gentle" if you want to win. A squirrel (and admit to those tendancies) can put on a real show but, like drifting, it is not fast. The real competition can go fast but makes it look slow.

Unless you are on dirt "turning left to go right" just serves to wear tires out real fast.

Driving rigs is similar. Innatention and poor maintenance can lead to trailer whip which is Not Good. As is racing you drive where you will be and not where you are. Anything you do suddenly is wrong.

Have driven everything from 400 cid V8s pulling a tandem axle trailer with race car, tires, tools, and spares to a VW camper over the Rockies. One thing they have in common is that I drive on the temperature gauge and how the rig feels, not the speedo.

Am somewhat of a fanatic about running engines cool, 180F is plenty to be "all in" for a computer car and everything lasts longer. Pulled the Judge on a tandem over the pass at Monteagle in mid-July without exceeding 200F. Have never needed more than a HD stock radiator either but tend to tune very precisely.

All that said, most medium trucks in Europe (e.g Transit vans) use 2.5 liter diesels. My Vixen has a 2.4 liter BMW TD and rolls at 6300 lbs. Won't hold up traffic at a stop light but the key to long distance travel is more not slowing down than how fast you speed up.

Before the WK2, my tow car was a 3800 V6 minivan though today I am more likely to use a dolly than a tandem. I do have a "2nd bedroom" for the Vixen but it does not weigh much.

Today with lockup transmissions, a mojor source of heat (torque converter slip) has gone away and the Pentastar has more HP than many of the V8s I've had.

Bottom lime, I'd have no hesitation about towing jst about anything with the V6. A Hemi might win a tow car race but will really not make that much difference in the long run.

Am surprised that Jeep did not put more into the towing package for the V6 though, may look into whether a V8 radiator has any more capacity & bringing in the cooling fan sooner (or just add a boost fan in front) Orlando tends to get a bit warm in the summer.
