Hello, new member and new owner of a Marco Polo. It was great to have our first night away this weekend to learn as much as we can about the MP. One quick question, I’ve bought a shower attachment (not the Westfalia option) for the rear shower connection and the water pressure was pretty hopeless. Literally not much more than a dribble. What I don’t know is whether this is a) normal b) a shower attachment issue c) a water pump issue? Any suggestions welcome from experience? Thanks, Michael.
