Took a longer look at this.
Idea is good BUT
videos that I looked at for water systems were generic forest river using (I believe) a Birkshire. NOT RELEVANT TO A DYNAMAX DX3
Location and placement of water system controls is completely different.
A statement that "Fresh water drain is normally below the lower skin covering below the fresh water tank" (or something of that nature)
Not so on a DX3 37TS. It is in the water bay on the left wall and clearly marked.
The manual needs a lot more work and must be relevant to the Dynamax products.
