Casette Toilets

We got a new folding trailer since I lasted posted in this thread and it has a cassette toilet. We really wanted the unit with one because we had one on a 1995 Coleman that we had bought new and loved it. We hate the new one and I usually don't use the word "hate". You have to be careful or it burps! It just seems it fills very quickly, obviously smaller than the other one. It has a swing-out access to get the black tank out and it is a pain! It seems like it is impossible to get clean and the other was so easy to keep clean. I guess they aren't making them like they used to. We are SO disappointed with this. Truthfully, we bought a new portable Thetford and it is not much better. I believe the plastic being used is not of the quality it used to be. For backup in the house where we have one toilet, we bought the Coleman one with the bucket and at least, it can be cleaned easily and the cleaning if effective. I am SO tired of inferior products at higher prices.
