I am looking for equipment suggestions for the following project situation.

We have won a bid on a duplex house that will have a detached garage. The service is to be located on the garage and will be fed from overhead powerlines that are located in the alley just behind the garage.

We are looking at one weatherhead that will feed both services for the duplex. Each duplex will have its own 200 amp 3 wire service. I am familiar with multi family dwellings that use meter stacks that all connect together to a single feed point, but I have never done a duplex before. Is it better to use one of the square d products and have a meter stack with 2 meter housings on it or is it more cost efficent to use a nema 3r gutter and then drop down to both of the seperate meter housings?

I am looking for suggestions ?

Thanks

IMHO, a duplex meter pan w/OCP would work fine. BUT, what does the local POCO require??
