I can pump at least 100 feet with my sanicon, but be careful what you put down the drain. Last year we had our first(and I hope last) clog while on a trip to the Keys. The pump kept blowing the fuse because the macerator impeller was jammed. One of the female guests decided it would be okay to flush a female hygene product which jammed the blades. My sanicon in mounted inside a bay behind a stainless steel panel and the slot for using a screwdriver for clearing jams in not accessible. I ended up removing the 3" line and just dumping with a stinky slinky until I could get home and fix it. I've had the exact same system on two of my offshore fishing boats and they work great if you don't feed them the wrong things. You REALLY don't want to have to take that 3" hose off between the dump valve and the macerator when it's jammed! If you put one in you coach, just make sure you can get to the back of the pump if needed.
