I had this problem awhile back. Check vent tube, no problem. Replaced AAV's, still had smell when camping. Read a post about cleaning gray tank. Tried it and smell gone. Take a cup of liquid dishwasher detergent and a gallon of hot water. Put in tank before heading to campground. Dump gray tank when arrive at camp. Repeat if necessary. This worked for me. YMMV.
