hi everybody. i found those hot and cold water lines. on my rv, they are located near the outside edge of the coach in front of the forward wheel on the driver's side. the black and gray outlet's are forward of these lines. the hot and cold lines hang down about 3 inches. my fresh water drain is behind the rear axle on the driver's side. it hangs down about 6 inches.
as a note, i thank everybody for their help. i must also say that i had called dutchmen customer service of help as i was posting his help message. i was told by this guy there that there was only the one drain located behind the rear axle. i asked about hot and cold water lines, but in his looking (?) at the coach's schematic, he said he did not see any other drain lines...was he ever WRONG.
but, all is well now. and again...Thank you.
