This is not an exact match, just sharing my experience.
A few months back we purchased our 2018 Jeep Wrangler 4 Door JK, it has the 3.21 with automatic 6 speed transmission.
We have a 6x12 enclosed v-nose trailer
We took some scrap metal to the junk yard/recycler.
I did not feel comfortable at anything over 70mph on the highway.
MPG was 13.
I agree with nydiesel, I wouldn't want to travel up north 8 hours pulling this trailer, maybe if I kept the speed at 60 mph it would be ok ?
We have a 14 foot aluminum boat.
We pulled it about 1/2 hour to indoor/winter storage.
I'd say our Jeep pulled it so well - I hardly noticed it was back there.
In upcoming May and August 2021, we will be towing our boat 8 hours north.. fingers crossed our Jeep will pull our small boat as well as our Chevrolet Traverse did.
