total maintenance, gas consumption? benefits or penalties?

THanks all....

My experience is that a single is easier to maintain, so it is more
likely to be more reliable.

It is in the center, as twins are out at the edges. Easier to get to
everything. One of everything instead of two.

Cheaper to run, cheaper and easier to maintain.

As for handling in close quarters, twins are better, but there isn't
much I can't do with my single engine.

A thruster would fix that, but it's an added complication.
