The dealer and Cedar Creek says for me or them to replace the Hepvo trap under the shower with a standard P trap. I can't see how a trap under the shower will help the kitchen sink drain out when the holding tank is completely empty. I have ran water down the vent from above and it flows fine. Since I don't know anything about my plumbing would you explain how replacing a drain trap under a shower will fix water not going down in the kitchen sink?

In your original post you said "When you do dishes in the kitchen sink the water won't drain unless you take the check valve off under the kitchen sink which is under alot of pressure.". Could that check valve be another Hepvo valve instead of a p-trap? Sounds like your system is having some sort of air lock problem. If you put a p-trap in the shower, then that shower drain pipe will get air and be able to drain toward the sink. When you took off the "check valve" you also introduced the required air that was needed for that water to flow.

Remember those drinking water coolers with the water bottle on top? If water bubbles don't go into the bottle the water will not come out of the bottle. Same principle. You need air.

I need to stop here since I don't have detailed knowledge of your model - you need help from a CC owner. But I will add that if the dealer does insist on a p-trap in the shower - ask if the suction will drain the water from the p-trap - if so you could have sewer smells in the shower. Good luck.
