We have a 09 Jayco Seneca, super c,Duramax diesel, and just took a trip towing a Honda CRV. Brake Buddy auxiliary system, Blue Ox Aventa Lx towbar.
We towed according to Honda specs in the owners manual, key position, cycling gears etc. The problem we had a few times was with the Honda locking the brakes up, even on the lowest sensitivity setting. We called Honda, and they recited what was written in the owners manual. Any answers as to have the brakes not lock up ?
