Trailering 4dr

Just picked up a hauler for the jk. And wanted to see if anyone has compared gas mileage, towing there 4dr jk with doors and soft top on verses with just a bikini top on - no doors?

The JK has the aerodynamic stylings of a brick.

I don't think there's much you could do to improve towing MPGs outside tarping the whole Jeep to try and cut down on wind resistance.

This I know. Just have two long hauls coming up and gas, well is a bit costly. Any savings will help.

Just for giggles, I checked my mileage for the last week running without doors and top...... it was around .5 MPG less than running full doors and soft top up.

I think the added resistance of the wind coming into the Jeep without the doors hurts more than the added weight of running with the doors.

And yes, I calculated the MPG's the old fashioned way. Not by using the crappy display in the dash.

I would imagine that towing the Jeep would net similar results.

I get best milage with my Jk driving with the hard top and doors on
I've only towed my Jk with soft top and soft doors on, my tow rig is a 03 chevy 2500 hd with a ladder rack and tool boxes it gets 10mpg if I'm towing the jeep or just driving around town no trailer
You might do better with no top no windshield but I like packing the jeep with stuff and not havin it blow away

Not much difference in towing mine but I got a little better mpg with the doors and top on.

Windshield down, seats folded down, rear glass open. Cut down as much surface area as possible... I've never towed mine but it makes sense.

I trailer my Jeep to faraway trails and have not noticed a difference in MPG with top up or down.

But I do know this, I get better gas mileage trailering my Jeep with my truck than I do driving my Jeep
