Sewer hose length and support recommendation

IMO, Executive has the only real good answer here. If you don't have a Macerator, you should get one. They are small, easy to handle, very little storage, and work at the simple touch of a button. The hose is only about an inch in diameter, coils up to less than 1 sq ft of floor space, extends to almost 30 feet and with the simple addition of a length of garden hose for further distance, can be pumped up hill, sealed with a simple little cap when not in use so no need to remove, clean out and store, can be permanently installed, and uses suction to remove everything from the black tank (no gravity required).

I can't believe all of those who still use a stinky slinky. They are so outdated, dirty, hard to handle/support, take up lots of storage, difficult to clean out, smelly, gravity operation required, and just make the whole process that much more difficult and unnecessary. ugh!
