Regarding Bob's comment about documentation in the owner's guide, I would like to say a hearty AMEN. As is true with other makes of motorhomes that I have owned before, PC gives you a bushel basket full of manufacturers installation and operation instructions and a very generic Intro to RVs 101 manual. It is not specific to the particular model you have and has no wiring diagrams anywhere. Also, there is only the most rudimentary guidance on the use of the macerator system, but that is pretty typical of what Thetford offers on line. They also believe one set of instructions fits all, whether you have a built in system from the manufacturer or a portable add on. I LUV my PC, but really would like a little more info in the form of a manual. Just as another example, I have no idea where my water pump is located. I suspect it's under one of the beds, but when you screw everything together, you have to come to forums like this to find out. Just having some of this documentation available on line in a customer support section on the website would be one great leap for us owners.
