First let me say it's not in the whole coach. It is just in the rear bath, the shower. The shower has really low water pressure. The kitchen and middle bath are fine. any ideas before I start tearing it apart?

Low water pressure is usually from a clogged filter or aerator on the faucet. The fact that it's also in the shower but not in the rest of the RV sort of eliminates those two usual causes. Do you have a momentary 'surge' of pressure, then it drops off? If you have a water manifold, check that the valves for the low pressure areas are opened all the way.

If you are sure you are getting full pressure to the coach, as Bob said could be build up where the shower line screws into the outlet, where the head attaches as well. Keep in mind there could be a restrictor on that line as well. Next, make sure the outside hot/cold in the utility bay are closed, if one or both are open, they share the same lines and your water will not be as hot and low pressure. Last, use cold only and if good pressure, flip over to hot only, if low pressure or any type of chatter it will be the check valve on the atwood water heater. This was our cause. There is very limited access to the valve from the left hand side of the bathroom vanity, remove the covering (velcroed on) and remove the access cover. Our RV tech said nuts to that and just removed the heater and changed out the valve. Under warranty of course. These valves have been prone to failure. Let us know!

I have this same problem in my 2014 40X.

Depending on what type of shower valve was installed, it may be as easy as unscrewing the wand hose from the valve and seeing if the orifice in the fitting that the hose screws onto is clear. I replaced my valve after noting how ridiculously small the orifice was even un-restricted (about 3/32" in diameter). The new faucet/valve supplies significantly more water to the wand.
