I used Rinoflex for two wear out cycles now have the Tethford "Smart Hose" and really like it.. It is different.. Sewer Master or Drain Master (forget which) is the best (And most expensive) but it is the last sewer hose you will ever buy (Lifetime warranty).
What am I using now: The one the dealer tossed in for free 11 years ago.. I do not often use it, but on this site it is the EXACT length I need, no other hose in the RV can say that.
Page 2: Sewer Solution.. This device is a fresh water powered Jet/Macerator pump.. Water is becomming more and more scarce, plus in some states, the water is all owned by a company such as Nestles or CocaCola. I can buy Coke's bottled water just 3 miles down the road for a mear 12.80/gallon... Thus I would rather not place the added load on the park's sewer system or water supply by using the Sewer Soultion.
Electricity in this country is plentiful, plus many RVers use solar panels to soak up a few hundred watts of sunlight.. Flo-Jet makes a portable macerator pump, electrically driven.. Works great, Works even better/faster/farther/higher than the sewer soultion, It has only one problem easily overcome (The rotor sticks if not used for a long time, they provided a slot in the other end of the motor shaft you can turn with a quarter or screwdriver to free it before you apply power).
I like mine. I added 50' 3/4 inch black rubber hose for the long runs to the hole in the ground. Works great.
