I think you hit the nail on the head... MY JKU is geared with 5.13s. 80-85 is within reach, but not for long. It spins just under 2800 at 70MPH. I set the cruise at 72-73 (3000 RPM) and she pulls an average of 15-5 to 16 with the trailer and 16-17.5 alone.

This is also my beef with rarely seeing 8th and never seeing 9th. I think Jeep did a piss-poor job of gear selection for KL TH 3.2L

7th is my cruise gear. I don't think I've seen 8th in over a year.

6th while towing and no wind.

I think jeep missed a few points with the Cherokee in regards to gearing/towing. But they were trying to build a vehicle that could fit a world market. It's okay at everything and good at very little. Fuel economy is okay. Interior quality is good. Ride is good, handling good.

My towing economy is what has made me wish I had gotten a 4Runner. At 6mpg I can't tow my trailer to Washington state because it'll cost me 800-1000$ in fuel one way and if I hit a headwind it can cost me 200-300$ more in fuel. So now I'm limited to 100-200 mile trips which was never my intentions. Makes me want to sell my trailer but I'm far to upside down now.

I have to wonder if "something else" is going on. Your fuel economy WILL definitely take a hit at 72Mpg, but:
- JKU only saw a 1% drop with the same setup(? that doesn't make sense)
- Same 12Mpg at 45Mph (trails, stop&start?)

I would be OK with ~12Mpg fuel economy when towing. The killer is the size of the KL tank, but your trailer lets you carry extra. When I was towing with my Ram 3500 and a 5,500lb trailer, my mileage went from about 19Mpg down to somewhere around 10Mpg, and that's with my preference to avoid 65+ Mph.

I think there is a missing piece of the puzzle in here, but I don't think that 12Mpg should be considered "bad", all on its own.

I'd love 12mpg while towing. It's only 4 lower than my average without a trailer.

The only reason the KL can outperform the JKU is arrow dynamic advantage, it keeps the load at reasonable hwy speeds to a minimum. They weigh just as much as a JKU so should probably have the same 3.6, the 3.2's power curve is utterly atrocious... No power down low in the rpm's... The reason your not seeing the losses while towing with the JKU is because you've already taken the hit of low arrow dynamics coupled with a drivetrain that's better suited to keeping the RPM's a bit lower while still having enough power to keep you moving. None of this changes the reality you're dealing with... By the way, your complaint is EXTREMELY legitimate, and is the reason I haven't sold my Kia Sportage, same size, smaller motor, WAY more power, AWD, and I average 31hwy... To bad it just not capable off road... Oh and with a 2200 pound trailer I averaged 22hwy. When I bought my jeep I remember thinking the widow sticker fuel economy is pretty close to what my Kia said... Surprise! Not even close..

When towing the KL behind a 400 HP turbocharged Cummins, moving up to 70 mph from 65 is a 1.5 to 2 mph penalty depending on head or tail winds. Nice looking trailer @SS_Syndicate. Does the cover over the top fill with wind? Could it be acting like a drag chute?

We travel across the country at 65 mph regardless if the limits are higher. I don't recall drivers getting angry as long as it's in the right lane. In cities where the speed limit drops to 65 or less I move it into the middle lane to avoid mergings at entrance ramps. I usually pick a tractor-trailer that's pegged at 65 (becoming more of a challenge with low fuel prices) and stay behind him/her. Easy driving and most drivers don't try to squeeze between us.

I consider 12MPG bad because a vehicle I own (that should get far worse) gets much more.... My window sticker showed a highway fuel economy of 26mpg with a combined 22mpg. This is the first vehicle I have ever owned where I was unable to achieve those numbers. We are lucky to see 18-18.5 on the highway. Our JKU's ('13) window sticker showed 21 highway and 18 mixed. We had no problem exceeding these numbers, and even with all the mods get fairly close to them.

I have a real problem with adding a trailer (of any shape) that is less than half of the vehicle's rating and seeing numbers that are more than 60% of the stickered economy. In truth, I have an issue with the actual economy given what it's advertised for all the time, but seeing it get this much worse is literally heartbreaking.

I agree the comparison to our JKU doesn't make sense, It's my whole issue

We did plenty of trails, but I removed them from the average. The 45 was an average as well. It was on the roads in/around the forest we were exploring.


The trailer does have fuel, but it wasn't to make up for deficiencies with the KL performance. We often have times where a 350-400 mile range is needed. The ~18 gallons we carry are to extend our JKU to this. I never thought this wouldn't be more than enough with the KL.

I get 22-26Mpg on the freeway with the Gobi rack. If you are lucky to see 18Mpg, I go back to my assertion of "something else" going on.

@edge600

Our JKU hits the scales when loaded out at 6300 pounds. Our KL when I hit the scale with the empty trailer for tags was 4800. So there is nearly a ton difference, but I hear everything else you are saying.
@Array

No, the top stays just as you see it. It is zipped all the way around the bottom and it pretty heavy fabric, it doesn't even flap.

Also, Thanks on the trailer complement.... a few have made one so thanks to everyone. I was just keeping to the grumbling at had LOL) Now that I've derailed a bit... It was our winter project. You can see the build HERE if you want.

I agree, but those numbers seem to be supported by others here... We flipped 10k miles on this last trip. Approx half of that has been on casual country drives and exploring, the other half is my wife driving 10 miles (one way) to/from work all interstate. We have NEVER seen a measured or calculated average over 19.6.
