The pressure regulator in my Safari is not the type that has a built in screen. I doubt yours does either. The screen in my inlet is right where the hose attaches to the trailer. It is part of the washer. Though, I don't know if is original or has been added by a previous owner. Both ODM and Inland RV show this same regulator that is in my trailer for a replacement on their websites. Lowes and HD have very similar regulators if you need a replacement, but you might need an adapter for each end if you get it there.
Are you using an external water filter or pressure regulator? If so, remove those temporarily, just to rule out that possibility that one of them is malfunctioning.
You say the problem in your trailer is at the kitchen and shower, but you do not mention the toilet and lavatory sink. If the problem is an inlet hose, pressure regulator, or inlet filter, every water outlet inside the trailer will have the same issues. If you are having a problem at only two fixtures, you can rule out these three issues.
I suspect there is a partially closed valve or a blockage at the faucets. First I would check out the winterizing valves on the water heater to make sure they are in the proper positions. Second I would remove the aerator screen at each faucet and clean it and let water flow in both hot and cold positions. Third, I would remove the shower head and flush the hose and clean the inline screen at the shower head.
If the above does not resolve the issue I would think about a blockage, even though I doubt there is a blockage within the pipes. But, it can happen if insects or trash gets in. I have seen sand and pebbles get into a pressure regulator, enough to block flow to every fixture. I had to replace that one. I use an external cartridge type filter to prevent this problem.
