Hi all, I have a 2011 Rpod 177 that we bought this year, we just got to use it for the first time, this past weekend, and we have a water issue I can't figure out, and need some help.

I have tried both ways, with water in the fresh tank, and hooked directly to city hookup.
My shower and commode water pressure seem fine, but the kitchen sink is pitiful. Not even enough pressure to wash your hands. I checked the screen in the little bowl attached to the pump, it was clean and clear. I played with the adjustment screw on the pump...nothing
All lines seem free of obstruction. Don't know what else to do, other than buy a new pump?
Thanks

Same thing happened to me.  Had lots of water in the bath but none in the sink.  Unscrew the faucet aerator on the end of the kitchen sink faucet and clean out the internal screens.  Mine were completely clogged.

Since then, I took a whole house water filter and modified it with hose ends to use while connected to city water or to fill the fresh water tank to keep sediment from coming back and clogging it again.

I'd suspect sawdust, shavings and other miscellaneous dirt has gotten into the lines.  Remove and clear out the aerator on the kitchen faucet.  If the clog isn't there, then there's likely something jamming around the taps themselves.  Unscrew the taps and have a look at the washers.
