I have a Sewer Solution.
While it is not a macerator per se, it uses a water jet to blast solid waste so it will pass through the smaller hose. I like it, but for my preferences, it is most useful for longer stays, where the black water would need to be "dumped" more than once. For shorter stays, I just use the regular "slinky" hose. Here's why: with the sewer solution, it does take longer to drain the tank. That slower drain speed has less ability to "evacuate" the black tank. The volume of foul water leaving the black tank with the slinky is more likely to bring things with it. Therefore, IN MY OPINION, the sewer solution requires more tank rising, takes longer to finish the job, uses a lot of fresh water (for the jet), and it costs more. That's all the negative stuff.
Here's the positive: the hose is extremely durable and won't tear (period), if I'm hooked up to a water pipe I usually don't care how much water I'm using, if I'm on a longer stay, I can pull the handle and turn on the jet and walk away (come back in 10 minutes to shut off the jet and close the valve).
Sometimes the slinky hose wants to jump around when I release the handle. The sewer solution doesn't have enough stuff passing through it at any one time to cause that, therefore, you don't have to baby sit it while draining.
