I am lucky in that I have some room in my engine room. When I relocated the battery chargers to the port side it left a nice wall to mount the control panel and twin filters. I mounted the other filter on the A/C shelve. The big high pressure pump and low pressure pump fit nicely in front of the STBD engine next to the fwd A/C unit. I still need to find a home for the membranes.
So now the plumbing and electrical.
