If I stay between 50 and 60, I can get around 12mpg, but anywhere above that and it drops down to 8 or so. My only complaint is going up big hills in that 50 - 65 mph range, as there really isn't a good gear in the transmission - either pulling high rpms or chugging along. Trading up soon, and can't wait to see what the 8 speed does.
Love the Surveyors. Checked them out at a show this weekend and had the best layout for what we are looking to do!

Re: What are you towing?

So, the diesel is rated to tow 6800lbs, but how comfortable to tow is it around that limit?

I have a Willys pickup that we are almost done restoring. It will weigh in around 3500lbs when complete.

If I load it into an enclosed Haulmark double axle trailer that weighs around 3300lbs, I would be right at that 6800lb limit.

The vehicle would also be carrying myself, my wife, daughter and a couple of suitcases.

Is pulling that kind of load -- possibly up some steep grades between PHX and San Diego or PHX and Flagstaff -- doable on a WK2 with the diesel engine?

You better check your weight again. That trailer is way over 6000lbs. Empty it may be 6000, but as soon as you put water, propane, and stuff in it it will weigh more.

Really take it to a scale.

I have lived though a barrel roll with a towed trailer. Not fun self-rescuing yourself, wife, then dogs. We ended upside down facing the way I was going. The trailer was 3500lbs.

I would check again I belive the towing cap. is 7200 or 7400lbs. I don't think the diesel will have any problems. You just have to set the hitch up right with a weight distrabutuion hitch. You wouldn't want to snap an axel because you overloaded it. Or void your warranty.

It's an ultra light, and only weighs 4900 dry. I'm just guessing we have another 1100 lbs of gear, etc. It might be over 6000 with the water tank full, but I'm not worried about it approaching the 7200 lb capacity. Would be interesting to take it over a scale though.

Here's a brief recap of my first towing experience with my diesel Grand Cherokee:

- towed a 25' Airstream from Las Vegas to Pasadena and back.
--GAWR Front Actual 3140 lb
--GAWR Rear Actual 3700 lb
--Trailer 6600 lb
--Combined trailer/vehicle 13440 lb
--Average OAT 60 F
--Propride 3 Hitch and Direclink brake controller

- EVIC fuel milage averaged 19.5 mpg to Pasadena and 18.4 on return trip
- Engine performance
--EVIC oil temp climbed to 257 on long uphill pulls (12 mile 6% grade)
--Coolant temp climbed to on notch below red area on gauge
--Slowing from 55 to 50 mph stabilized engine temps
--Temps quickly recovered on level or downhill grades
--Engine torque and power were not an issue
- Transmission performance
--EVIC transmission temp climbed to 203 once, but mostly stayed at 195
--Gear shifts were smooth and appropriate for the load (ECO mode OFF)

Overall, my first towing experience was very positive. The biggest limitation is tongue weight, especially if you are carrying passengers/cargo in the Jeep. I carried no cargo in the Jeep and you can see with full fuel and DEF I was max'ed out on the front and rear axle loading with just my spouse and I in the Jeep. A good weight distributing/anti-sway hitch and brake controller are a must.

You are correct, it is 7200lbs. for the 4x4.

Thanks! One thing that might concern me, is that you stated the outside average temperature was 60F. We only have those temperatures for two months of the year here in Phoenix. I could very well be facing outside temperatures nearly double that. I wonder how much more that would negatively impact those oil, coolant, and transmission temperatures.

I really wouldn't worry about the transmission oil temp. The ZF German built 8 speed unit is a great transmission. My oil temp hovered right at 195. The VM 3.0 is another matter. Some say don't worry about it as the small diesels normally run hotter than their big brothers. A Chrysler mechanic who just received training on the new VM engine said oil temps below 275 are nothing to worry about. He said the engine will "detune" itself to keep the temps in the normal range if necessary. Chrysler is mum on the subject and the owners manual pretty much just says "slow down" if you start to overheat. I guess we'll have to wait and see how the new CRD performs over the summer towing season.
