I bought a new '11 Ford Explorer Limited so I could tow it flat. It is loaded with everything but a moon roof and back seat DVD player. I have always used Blue Ox and was happy when I found that Blue Ox had tow bar brackets for this new vehicle. I have adaptive cruise and Blue Ox has a DIFFERENT bracket set than for the 'regular' non-adaptive cruise '11 Explorers. Ordered the correct tow bar brackets and had it installed. I then tested out the vehicle with installed brackets by hooking up behind my motorhome and towing it for about 20 miles. It worked flawlessly. This unit does NOT have a key but instead is a 'push button'. There is a procedure to put the 'button' into 'accessory' which I did, then per the manual I put the tranny in Neutral. Off we went and it worked well. I had the proportional Brake Buddy in the vehicle while I did my 'testing' AND had my wife ride in the passenger seat to see how everything looked and sounded as we towed. Worked great.
HOWEVER, later when I unhooked and drove the Explorer I started to throw 'error codes' on the adaptive cruise which effectively meant I no longer could use either normal OR adaptive cruise. I went to Ford to have them 'clear' the error. They could not do such and said the problem was caused by the 'after market' install of the Blue Ox. They said I'd have to take the tow bar brackets off before they could calibrate and adjust the adaptive cruise control radar unit. I went back to the installers and they couldn't find anything wrong with the install but took off the stuff they had installed. I then went back to Ford and they worked a few hours, got the error cleared, and charged me $250. I called Blue Ox, have talked with Ford, and have talked with my installers. Everyone kind of pointed to everyone else, BUT each of the three entities IS willing to work with me to find a 'cure'. At this point I'm going to drive the Explorer for a couple of weeks to be sure no error code is thrown with the brackets off--if it does then I think we have a Ford Problem. Then after a couple weeks I'll have the installer put the tow bar brackets back on and see if we still have a problem. If not, then I'll caulk it up to a quirk--if still have problems then I will deal with the installer and Blue Ox to take back the tow bar and reimburse me and will see what Roadmaster has.
Since the Ford Explorer '11 is a new frame, new engine, new tranny I'm hoping Blue Ox sells a few more and we can see if we have a systematic problem or a quirk. Also, if you are considering buying a '11 Explorer to tow be aware that the 4 wheel drive vs the 2 wheel drive have different 'abilities'. I went with 4 wheel as it can be towed flat, but NOT on a tow dolly. The two wheel drive uses a tow dolly but can NOT be towed flat. Both of course can be towed via a trailer.
All in all I really like the '11 Explorer Limited and want it to work with Blue Ox plates for towing. I went with this over several other brand vehicles as the Ford is the simplest and easiest to tow--no fuses to pull and the only restrictions are 65 mph limit, and run engine and go through a gear shift routine (from neutral to drive, to reverse, and back to neutral) every 6 hours or the beginning of each day. The the Limited is loaded with neat electronics BUT that comes with its own set of problems.
If any of you with the 2011 Explorer AND YOU HAVE ADAPTIVE cruise, AND have installed either the Blue Ox or Roadmaster I'd be interested in hearing from you at hsteinle@hbsteinle.com or harlansteinle@garmin.com
