The problem with the Maquis was that the source of their conflict, the DMZ, was now 75 years away. The Maquis were the enemies of Cardassia, not the Federation, and whatever negative feelings they had for the Feds wasn't going to blind them to the fact that these were the only familiar folks around for decades. It wouldn't have been productive for the two crews to be that combative to one another the whole way through.
And even if they were, the tensions would've died down after 1-2 years. If they kept it up after that, then they had to have serious mental issues and they'd likely never get home.
I could never fit into Starfleet. I would have been quite likely hostile to my forced absorption into the military had I been a Maquis member. I would have been one of the unseen folk scrubbing toilets and taking napes in the Jefferey's tube when I thought I could get away with it.
I'm thinking at least some of them must have rigged up a still.
