I have a 2003 Itasca Sunrise with very low water pressure in the shower faucet, all other area's seem to be okay. I replaces the faucet assembly to no avail, any suggestion's.
Most new shower heads have water saver piece in them. I take them out. Also check the screen in the water faucet to make sure it's clean. By eliminating those two things, I would again look at the faucet valves.
