We are new owners of a Sundance 3012RE and so far loving it with the exception of either low water flow or low water pressure. Therefore, we are looking for suggestions. When connected directly to city water (no regulator and no filter) we don't seem to have very good pressure or flow. We can definitely notice it when taking a shower or using bathroom faucet. Can anyone assist us to helping figure out which it is, please. We have only been camping two years and this is our first year with new coach and located at permanent campground, Looking forward to hearing feedback.
