Aluminum roof ground necessary?

[Gashog]

I've Googled 'till my head hurts.
I've asked on other forums.

I restored a 1984 Sunflyer about 8 years ago.
It's about ready for another dry dock but no one wants to take road trips with me anymore.
I figure it'll make a good ham shack/office but I need one question answered first;

Does the aluminum roof need to be grounded to chassis?
