Hi Tom, welcome to FiberglassRV. We have had a couple of Dolphin owners here... not sure if any are still active at this time. I checked the album and only see one picture! If your trailer is basically stock, please post pictures and eventually the pics may be added to the brand album.
We don't seem to have an owners manual for the Dolphin either. But, there are tons of other documentation that you may find helpful. Check out the Document Center here: Fiberglass RV - Document Center
