Low water pressure inside the coach
2002 Winnebago, Sightseer, 27 foot. Water pressure inside the coast has slowly decreased, kitchen sink, shower, bathroom sink. Did Winnebago install a pressure reducer someplace in the motorhome?

Are you on city water? If so, do you see similar pressure reduction when on the pump?

If on city water, check to see if you have a debris screen located where you connect the hose.

Yes, I too was going to suggest that when confirmed that you're on city water. If you see greater pressure when you're using the pump, then obviously something is wrong with the incoming water supply such as a clogged screen/strainer, etc.
Also check your own pressure hose-attached regulator if you use one as I've found the cheaper ones will sometimes get clogged and/or eventually "go bad" and reduce flow to an irritating level. I've used some that have done that.

All locations also usually have home type flow reducers that can have multiple metal screens and plastic reducers that plug. Remove bubbler and take apart take a pic of order its easy forget.

Agree with the above re washer screens. Check every where you have a water connection between the water source and the RV. There may be several screen type washers.

Take off the faucet heads and shower head. Check them for sediment, as these many times will clog over time. Soak them in white vinegar and reinstall.
We just did all in our coach and it is part of routine maintenance.

We forgot to replace our whole house filter one year and water pressure in the coach decreased over time. Replacing the filter corrected it.

I'd pull the whole house filter and then try it, assuming you have one.
Fun story - a neighbor had trouble with his power washer. Couldn't get good flow. It would start to spray then simply slow until it nearly stopped. He was getting ready to remove and rebuild the pump of the washer.
I pulled the garden hose off the washer's inlet, then turned on the water at the spigot. The water started coming out just fine and then slowed down. I shut off the water and looked into the end of the hose - two eyes where staring out at me.
Seems a frog had ventured into the hose when it was lying on the ground. When the hose was hooked up and water was turned on the frog acted like a valve. The frog did not survive the experience... sad story.
Moral; connect the ends of your stored water hoses to themselves to prevent critters and debris. Do the same for your air hoses that you might be storing. {I don't bother doing this with my extension cords as I don't think the electrons will drip out.}

key in the diagnostics is if when you first open a faucet that you have good pressure, and then the pressure quickly falls off. If this is the symptom, then you have a restriction that is keeping volume of water from getting to the faucet (ie: check the filters / screens for partial blockage). Check all faucets to see if all are bad. That will start to pinpoint where the blockage is. If all, then it's at the water source (fresh water inlet).
