The SUSPA C16-08054 is a gas pressurize cylinder like you would find on a regular screen or storm door. In the T12RB it is attached by screws on the bottom of the rear bed and to the front side of the bed frame.
Yesterday I raised the rear bed to see the storage area underneath and the part in question expanded to support bed and allow access to the storage area. The problem is the cylinder would not contract and I was forced to unscrew the part to lower the bed again.
I have tried numerous times to get the cylinder to go back to its original state but to no avail. Another thought is the part may be defective and needs replaced
Any suggestions?
