Manson supreme on a bav 30 cruiser?

[Irmascherkid]

Hi all,
As with various other topics I'm sure that this one has been discussed in great detail in various other posts, but as I fail to find the answer I thought that maybe someone would have already been successful in this.
Question is this I am looking to replace my box. Standard qcr for a more trustworthy piece of ground tackle and have seen various post debating delta, rocna etc but having looked at the Manson supreme I was curious as if any one with a 30 cruiser has installed one of these and if there were any issues regarding the bow roller and chain locker hatch?

As always any sound views are greatly appreciated.
