water seems to come out fine everywhere except the kitchen sink

If that is the only place you are have an issue, I wouldn't think it would be you water pump.
Check your supply lines for a clog. With the spray faucets, it doesn't take much to clog them. I've have to tear ours down to blow out the tiniest of dirt particles.

Get a bucket and pull the supply line off the faucet. Point the supply line into the bucket and have someone turn on the water pump and see what the flow is.

We will when we find a tiny elf, lol - Bob can't reach under there - looks like I'd be giving it a go.
I still think it's the pump. We're going to hook it up to the city water today and check it out.
Actually I decided the issue is everywhere, it's only 'acceptable' in the bathroom, And I remember our old coach had nice water pressure everywhere. I was forgiving it too much because it's a small coach and it's a RV not a house. But our old Winnebago had MUCH better pressure when using just the pump - I remember turning on the pump to wash my hands at rest stops - and it was fine pressure. It feels more like "roughing it" in this Newmar. Last trip, I actually kept a bucket of water in the shower area to be sure the toilet is rinsed, and for washing dishes. This is ridiculous. Pump!

I’m on my second Newmar, and both of them have issues with kitchen water pressure. I have no idea why.

I don't want to hear that! One thing I did notice is the very tall faucet (gooseneck?) and I wondered if it just has a wee bit too much height for the pump "head"? Is that what you call it?

This has the same flow from either the hot or cold? If it is the same for both hot and cold then the problem is in something common between the two. Pull the valve assembly apart and check for debris in the holes and also check in the ball too.

same in both hot and cold

When my whole house filter needs changed the kitchen faucet is the first to slow down. And it seems to need changing a lot more than it should after already going through a filter and water softener out at the faucet.

We were testing it with no filter at all. With city water at our house. Still a thin stream. Just put it a new filter - no change.

We're getting by - not enjoyable, but it's tolerable. Christmas trip right now.

Check to see if there is an inline water filter below the sink. Depending on how they plumbed it, it may be filtering the sink and then on to the fridge.

I don't see one. And btw, I'm listing what I know, again (it helps me).
Water pressure (wp) was fine ... in kitchen, bathroom sink, toilet, shower, during our 18-day trip from Oregon to Tx in September. (stayed at several diff campgrounds, hooking up to water at each).
Motorhome spent several weeks at PPLmotorhomes in November (I'm suspicious of them). We asked them to check out a leak in the wet bay - they said they fixed it (when we discovered they didn't fix it, we made them take that charge off the bill).
Next trip - poor water pressure at kitchen sink and bathroom sink and toilet. Shower was ok - never a gushing waterfall. but normal for an RV - we can take showers and even wash our hair.
Pencil stream at sink and bathroom sink, and toilet is unenthusiastic (I keep a cup and a bucket in the shower just in case ), but adequate.
We had an RV handyman take a look - he says the fittings are all too small in the wet bay and he wants to rebuild that area. I'm thinking that maybe the PPL folks messed it up.
Anyhow, we're getting by, but I'm thinking too-small fittings - but how is shower doing so much better?
I'm a serious cook, and really hate the pencil stream in the kitchen.

I know this is no help, but I just have to tell you about our kitchen faucet that didn't work when we brought our new RV home. All the faucets worked fine except for the kitchen. I would push it one direction for hot- nothing. Push it in the direction of cold- nothing. Trouble shot everything possible and still nothing. Was on the phone with the dealer for I don't know how long. FINALLY- I think by accident- I pushed the handle sideways and guess what?!? It worked. Just like yours looks like in the picture. Jeez. Sometimes wonder how I survive in the real world.....

Oh yeah- we have the exact same fixture. If everything is working right, the heighth of the stem shouldn't matter.

I have often found hotel shower faucets to be a challenge to operate.
