1929 CCPU Top Assembly

[Rex Perry]

I am building a 1929 CCPU and have completed the pieces for the wood top. I am considering putting the wood pieces together on the truck with some glue which would allow me to deal with the top as an assembly instead of individual pieces.
Painting the top would be a lot easier as an assembly but disassembly would obviously be more difficult.
Is there a good reason why the wooden top pieces should not be glued together?
