I got some expensive news from the Blue Ox tech this morning at the Hershey RV show. I was looking forward to a $25.00 rebuild like the guy next to me just received on his really worn looking bar. Our 4 year old Aladdin tow bar was deemed "shot" in his words. Even though it looked like new, the aluminum bars were coming disconnected from the ends that attach to the TOAD. Coincidence that the new ones use steel rather than aluminum? The replacement parts cost $600 to replace both. I traded in mine on the spot for a new one.
It kind of stinks having to replace a bar only 4 years old with only about 12,000 miles on it.
I've always stored it inside and covered when not it use. I'm sure the tech was being honest with me (he did just rebuild a much crappier looking one next to me for $25.00). I would consider this more of a design/manufacturing defect than wear and tear. The parts that broke are not moving or lubeable areas and no maintenance could have prevented their failure. Blue Ox also makes those parts out of steel now.
Just a warning to all those with aluminum Aladdin tow bars. Get yours checked out no matter how nice and clean and new it still looks. I was told mine could have failed at any moment.
