People's eyes always pop when they see this...
And I have to smile when I answer the inevitable questions of, "does that Jeep really pull that?"
It's a 27' Surveyor, supposed to be 3900# dry. Last summer I weighed it (with a full tank of fresh water & 2 full propane cyl - empty gray & black tanks) at 5600#. I'm definitely stretching the limit.
I use the Hensley Arrow and it's stable at 65 mph. I can't say how much better or worse the $3k hitch makes it because I've never towed (this trailer) without it.
On a fair day I get 13-15 mpg out of the combo, I've pulled up to 17 and as low as 12 mpg. (By comparison I had a 2004 Hemi Durango that pulled 10 mpg and a 2002 gasser (patooie?) KJ that pulled 9 mpg.) I keep the cruise at 65 mph for 2100 rpm in 4th. She don't really like pulling this in 5th.
I've pulled about 6700 miles with only one issue, an engine overheat and power derate on I75 southbound from Cincinati (spelling?) into Kentucky. (but that's because everyone decided to stop at the bottom of the hill - if I could have hit it running with the t/c locked I think it wouldn't have been a problem) I just kept my foot on the floor and waited for the trans to overheat, then it locked up in 2nd gear (I knew it would). Once the t/c was locked she tugged up the rest of the hill at about 40 mph, screamin all the way.
It's a happy little tractor, and probably by far the most fuel efficient vehicle (no longer) available in the USA that can tug this much. Once it's paid off (and Suncoasted and lifted) it's tugging days are over - I plan on getting a Cummins - when I can afford it. Then I'll keep it around for commuting and mudding.
P.S. my parents have a 40 motorhome and toad their KJ. I keep telling them it's on the wrong end...
