I have a new Classic Polypro cover for a 178 that has never been used.   Will sell for $75 plus shipping.  I also have the plastic single gas bottle cover that is used on the 2017 models at $25.  It was removed from my new 179 in order to install double bottles.  I also removed the sewer tube and that is available with a brand new in the box stinky slinky for $25,  I have replaced that with the longer storage tube and a Rhino Flex hose.  

Lastly, I have a Dometic 3000 generator with about 20 hours on it.  This is designed to start and the Dometic 13,500 BTU AC units and does so with no problem.   I used this on my 178 but with the new 179 that I am setting up with solar panels for boon docking I now have no ac and no need for such a large generator.   This unit weighs about 70 lbs.   I will sell for $500 plus shipping.   It can be shipped UPS or FedEx.   Please let me know.
