We are sitting in our driveway getting ready to head to the Tampa RV Show in the morning. I'll hook up our city water to double check, but I think the problem is only when using carried water. I'll check and repost.
Our in house shower hose is quite flexible and easy to use. We love it/ I'm going to look at the Tampa show for a solution to the hose issue Looking forward to seeing Stuart, Amanda and the Phoenix folks. as well as the 2012's. Gotta check the hoses on the new models. Maybe Stuart will want to trade them out. "That is hoses" not RV's.
I believe the pressure problem must have been debris in the tank blocking the inlet, as it was okay when the inlet hose was hooked to our house. And it was okay at the Tampa Show using coach water.
I found a perfect new shower hose after returning from the Tampa Show. Bought it at Lowe's for $23. It is flexible and has good length and metal fittings.
