I thought I would share a simple way to protect your seats when the tower is down. When I purchased the my 220 bj25430 had build independent supports for the tower so the bars and the speakers would not ride on the seats when traveling. I have added to the idea and made it more stable. I did not glue any of the pipe together which allows it to be disassembled quickly for storage once you get to the lake. It works great and allows me to tow with the tower down and not damage the seats.
