If you have that much rot on the end cap, check the side board. If the bolts that hold the lift arms look "sunken" or crooked when lifted you might have a problem there also. I was intimidated at first but did some research on this and other sites. Repair went pretty smoothly. Good luck and take your time.
Most excellent, I had not thought of using one of those and have been looking for a reason to buy one.
The sides seem to be perfectly fine.
I was also considering building it up with fiberglass patches and resin.
Thanks for responding.
