I just don't understand the mentality of those who think they can't use the toilet in their rv's....or those who think they need chemicals to keep the odors down. Stories get started by someone who really doesn't have a clue and pretty soon that story gets passed on and expanded to the point that it becomes fact.
Texas Roadrunner....The only real difference between your toilet at home and the one in your rv the quantity of water required and/or used. So it just stands to reason that if you use lots of water when flushing the toilet or when draining the black tank, you can use the rv toilet just like you do at home. Granted, if you boondock, this is counter productive as it will fill the tanks very quickly...but you get the point, I'm sure.
Sensors are notorious for going bad, but I have found that when ever we travel, I will drain the tanks first, put about five gallons of water back into the tank and then put in a cup full of liquid laundry detergent. The motion of the rv going down the road will cause a cleaning action within the tank and pretty much keep the sensors clean also.
Don't be afraid to use your rv toilet...it's your friend when in need.
