Check that vent to be sure it is not clogged up. We use a product called Bio-Clean; which is an enzime that eats proteins (paper, hair and you know what) It does not have a deodorizer but we have not needed one.

Will check the vent and see if I can find the product you mentioned.

ALSO ON THE VENT TUBE, IT COULD BE THAT YOUR VENT TUBE HAS SLIPPED DOWN FURTHER INTO THE TANK AND HAS MATERIAL AROUND ITS' BASE. I HAVE HEARD WHERE NEW RVS. HAVE THIS PROMBLEM ( SMELLS- NO VENTING ) BECAUSE SOMEONE INSTALLED THE VENT TUBE TO LOW IN THE WASTE TANK. AL
