My Overhead Cabinet Fell Down - Is my Towing Setup Responsible?

lundi 25 août 2014

My tolerance for surprises is being tested again. Upon returning home from a long weekend with the AS I discovered that the entire “overhead” cabinet above the front panoramic window had dislodged from the wall and ceiling. It dropped all the way to the dinette table.



The cabinet had been fastened to the ceiling in three spots with 2 or 3 screws in each location. It was also attached to the wall above the window in a number of places. None of the screws were bent. It appears as if the whole cabinet just pulled out from the wall all at once. I inspected the rear cabinet, and discovered that it had dropped several inches on the curb side.



I'm concerned that my towing configuration may be contributing to this issue. When I received the trailer I installed a 6,000 lb. Equalizer hitch with 600 lb. bars. My TV was a 2005 Toyota Sienna AWD. I quickly discovered that towing right at the upper legal limits of this combination created a white knuckle experience that I wanted to eliminate.



Within the last month I have replaced the TV as well as the tires on the AS. I'm now towing with a Chevy Suburban K2500 4x4. The replacement tires that I installed on the trailer are Kumho Radial 857s. I had a nearby trailer place tweak the Equalizer to fit the new configuration. They did not have a drop shank tall enough to level the trailer. The nose of the trailer points upwards when connected to the truck – not a huge amount, but it is noticeable if you look carefully. I had some load in the back of the Suburban, but I was nowhere near the payload limits. The trailer weights 3,200 lbs. without water or waste as measured on a scale. It was probably just below the GVWR of 3,500 lbs. during the trip. The tongue weight is approximately 530 lbs. as measured by a Sureline scale placed on the inside top of the coupler. The Suburban's advertised curb weight is 6,419 lbs.



Could the changes that I've made be causing problems with the trailer? Or is the timing of this problem more likely coincidental? Do you have any suggestions on what I might do to reinforce the repairs?



I will greatly appreciate any comments or suggestions you have.
