little water pressure

I have a 72 International Overlander and was camping a few months ago in a State Park, hooked to the water supply and my water pressure suddenly went to a trickle on all faucets and toilets. I had no external pressure regulator.
Looks like there is some kinda pressure regulator in the rear hatch of camper. Is that something I can adjust or has it failed? or would that even be where the problem is? I am new at this and any info is very much appreciated.

There may be a strainer piped in before the pressure regulator. If so, take it apart and clean the screen. The pressure regulator may need cleaning, replacing or adjusting as well.

Hope is not a plan.

Both my '67 and '72 had failing regulators when I got them. They passed water, just wouldn't regulate.
I would also suspect a plugged screen in the city water hookup at the rear of the rig. The '72 has a check valve back there as well. I'd inspect the connection point back there first.
BTW I always hook up city/park water with a cheap inline regulator and filter. With all the plumbing issues associated with vintage trailers it's 1 less thing to worry about.
Good Luck,

This may or may not be the cause, but I feel I must offer a little advice to everyone. Bugs of all sorts such as earwigs and hornets like to hide or nest in cool, dark places.
Like the open end of a faucet. Let the water run a few seconds before hooking up your hose. Parks routinely check the quality of their water, but it is not possible to check each faucet between campers.

My trailer had a debris blockage in front of the backflow preventer. I removed the preventer along with the regulator and cleaned both. That solved the problem.

Eastern South Dakota is very pretty with hills, rivers, and trees.

Ya'll were absolutely right. Checked all faucets, they were clear. I took the backflow preventer off and it looked like a big wet squirrels nest on that thing. Cleaned everything out and it works like a champ. Thank you all for the replies and suggestions.
