When I am hooked up to a water line I always use a water pressure regulator with a guage just in case their pressure is too high.

The water pressure at the kitchen sink is horrible. I will check those filters at the sink today.

Hook a pressure gage up to your water system, turn the pump on and see what the pressure is. Your pump is probably rated at 55psi, if it isn't over 50 on the gage, then turn it up to at least 50psi. Two screws on the bottom of the pump, one for cut off pressure, one for by-pass pressure. Cut off pressure must be higher than by-pass pressure.
If you also have weak pressure hooked up to city water, most likely a blockage in the water system, go to the filters first.
Do all faucets have weak pressure or just certain ones?
Water pressure regulators are notorious for restricting water flow volume in addition to pressure. I have two pressure regulators in parallel to provide good volume, but restrict pressure when needed. Very seldom use it.

Yes. I switched to a Remco 55AquaJet ARV which draws 10 amps and is a 5-chamber pump that provides 60 psi @ 5.3 gpm.

Here's how it compares to my old ShurFlo (which I still have as a spare):

Weak pressure throughout but really bad at kitchen faucet.

If you haven't already, remove the flow restriction to the faucet. Also, check for kinked hoses under the sink, especially if you have the hose sprayer type. The weight that is used to hold the sprayer into the neck can be in the wrong place and create a worse restriction.

When we got our new coach from the dealer earlier this year the guy was showing us around and the water pressure from the kitchen was horrible. He said "oh that's common" and wiggled the hose underneath, and it fixed the problem.

Our kitchen faucet has a pull-out faucet so there is an "extension hose" for it under the counter, with a ring-style weight on it to make the hose retract nicely when you put the pull-out back. Turns out the ring was pinching the hose and preventing flow, and rearranging the hose under the sink just helped free up the flow.

Something else to check out

Great info. I will do what you recommend.

I will check. It is one that extends out to spray off dishes.

Probably part of the problem. Thanks.

Nope. My previous pump was already connected to a 10A fuse.

We have the sister unit from Itasca, 33c. No problem with water pressure in either mode with over 200 nights in it this year. Suspect a blockage or check valve not open fully. Time for warranty work to check it out.
