Towing Questions

1.) What role does "frontal area" play in towing. I see that the Ecodiesel has a frontal area limit of 55 sq ft. The BOX of the enclosed trailer I am looking at is about 96 wide x 80 tall. Does that mean the frontal area is about 53 sq ft? Or do I have to take the overall height from the ground?

2.) Does anyone know the GCWR for the Ecodiesel 4x4. The manual lists the GTW and tounge weight only.

The trailer I am looking at weighs 3200lbs. and the truck that would be inside it would be an additional 3500lbs.

We would be carrying about 600 - 700 lbs of people and cargo IN the Jeep and would have a brake controller onboard.

We would be traveling through rather steep inclines north of Phoenix or east of San Diego.

Is any of this even feasible with the Ecodiesel WK2?

1) I think you calculated the sq ft correctly and it's ok.

2) It depends on the model. You should be concerned with payload capacity. You need to subtract the tongue weight of the trailer from payload capacity and the rest is for people/cargo. The limited is 1270, overland 1170, and summit is 1050 (they are less if you have a 4x2).
as far as the trailer weight you are fine, its 7200 for all deisel models (once again assuming you have a 4x4). i'm not sure if this link will work but these numbers are from jeep.com:

i think you will be fine if the tongue weight isn't to bad, if you go forward please post your experience since you'll be pretty much fully loaded.

Re: Towing Questions

IMHO, you will be almost at the limits of your JGC. Both at GTW (passengers, "stuff" inside the vehicle and tongue weight) and, at approx 6700lbs, the trailer.

The sensible thing to do would be to load 'er up and then take it to a truck scale. Weigh the vehicle first, then the vehicle and trailer combo .

Thanks! It will be a while. The truck I would be hauling is still undergoing (the final stages of) a seven year restoration process, and I haven't even placed an order for the Ecodiesel yet. But just seeing if the Ecodiesel would fit my needs for towing.

I didn't want to go through the process of buying an expensive trailer if I had no vehicle capable of pulling it.

Re: Towing Questions

Your trailer will be 6700 lbs. It is generally recommended to load a trailer so the tongue has 10% of the total weight for best stability. That's 670 lbs. 700 lbs of gear puts you over the limit. My suggestion is to put some of your gear in the bed of the truck you are hauling and keep the tow vehicle below rated capacity.

With that much weight, you will want a weight distribution anti-sway hitch and electric brake controller, especially towing in hills with curves.

The 700 lbs. wasn't all gear... it also was a guesstimate of the gear AND the weight of the passengers. How do those figure into the tongue weight?

You need to determine the tongue weight with the truck in the trailer. If that's 670, you subtract that from the payload capicity. If you go with a limited 4x4, it will be 1270. so you will have 600 left over for people and cargo. so if you have 4 people averaging 150, put all the gear in the trailer as excursion had suggested.

Yes...well said. You can adjust the tongue weight when hauling a vehicle by moving the vehicle forward or back on the trailer. Finding a scale to measure only the tongue weight that handles that kind of weight is difficult. I've used a 10:1 moment arm (landscape timber) and a bathroom scale as a DIY solution....670 lbs reads as 67 lbs.
