    It is gravity feed. Last night we pulled the cowling to expose the plumbing. The feed hose was not routed correctly with the hose sloping down, then as hose curved around to the tank it sloped upwards. Corrected the angle of the hose. Secondly, there was something obstructing the vent tube. I blew into the vent hose and felt the obstruction give way, then a lot of gurgling and water came back out of the hose. Between the two corrections the tank is now taking water. All fixed!

Am I correct assuming this RV has no gravity fill and the fill is off the city water hookup? If so maybe try draining the tank and while leaving the drain open try forcing water backwards through the vent to make sure it's not blocked.
