Not sure I think it's a aqua flex it is rigid and the ends are more sturdy then the hoses at Walmart. Rhino is a awesome sewer hose but is a very tight fit in the square bumper and the bumper caps do come out. I put 2 5x5 fence post and 1 conduit box under mine I can fit rhino and small piece for my tote with ease.
Well, We've had two trips and have enjoyed them both. We can't store our TT at our home. Where do you rinse out the Rhino hose besides running water through it to the dump station? I'm also curious. Do you spray any water down the commode besides the flushed water?
