I have a 2000 3280 RL I have a horrible smell from the kitchen sink. I cannot find a handle to drain the galley tank. I have read most post here about where its located. I have crawled all under and around this thing and cannot find it. Any help or pictures would be great.

I have a different rig, but my kitchen gray tank handle is just above and behind rear tire on drivers side on the frame!!

Not sure on a 2000, but on newer rigs the handle has been on the street side either before or between the tires. On one model I saw it was actually in a small door above the wheels. If the 2000 has two tanks it's also possible that the handle has unscrewed and fallen off at some point in time.

I found it!. I had to remove the under penning. I found the valve but the handle had broken off. The handle usually is between the axles . Thanks all for the help.
Now just to tackle the bad smell in the camper.

Two things about the bad smell. Most times on newer rigs the kitchen sink has a spring loaded devise under the counter that serves as a vent, kind of shaped like a small plastic can on the end of a vent pipe. If it sticks open then you will have smell coming up from the tank. They can sometimes be taken apart and fixed or most box stores have them since they are also used in homes and restaurants at times. Also, you can use a product like Happy Camper on the grey tanks also to remove oders and accumulated food material.
