On the off chance someone here could use this, I have the TOP part of a two-part removable Atwood captain's chair pedestal/seat base. This came with a captain's chair that I bought to add a third seat to my SMB. I hate to just toss it in the recycling can if someone can use it.
I have it on Craiglist locally, but am willing to ship it to a SMB Forum member if you pay for shipping. Let me know ASAP, though, as I'll probably recycle it next week if no new home is found.

I also have a SMB OEM provided continental tire kit, including the metal surround and plastic "disc." Also free to a Forum member, but pickup only in the Philadelphia area as shipping it would be a pain (unless you want to pay to have FedEx Office/UPS Store pack and ship it). See
