I have emailed TM the same question/comment, and have never heard back. I too, think that if regen turns off when the battery is at 100%, they should be able to turn it off while towing with a simple software update. We need to be able to carry 5 people in the tow vehicle when we go RVing (7 would be better when we are with friends). We used to pull a Chevy Suburban behind our motorhome. Now we pull a Grand Cherokee. Pulling a full size trailer with a car on it is not practical since many campgrounds have no place for you to put the trailer. Between the motorhome and the boat (which is just over 5,000 lbs with trailer), we may be forced to keep the Jeep when the X arrives.
