If you have 2 part tramp and need to remove it every year, you may want to consider grinding a slot in the center of the crossbar. Newer H17 have with 2 part tramp -- look it up in on-line H17 manuals. My H17 is old style and I just went through disassembling crossbars and installing a new tramp, so I understand your pain. If you are you are doing it single handed, it is a half-day exercise. I could not imagine doing it every winter.
On the other hand, it is a good idea to inspect what is going on in hull-crossbeam connection. In my case, all bolts were loose, and one spot in the hall pocket needed get-coating.
Is your tramp diagonal type? If so, it must be old. I saw some good deals on basic 2-part tramps out there, you may consider.
