Thor Super C (Chateau/Four Winds) improvements and mods

well.... after using her a few times (and nearly 5k miles since we got her), few observations/questions... when I try to fill up the water tank it keeps spitting the water out and literally half the water ends up on the floor wasted vs the actual tank:(, 2nd issue, when connected to city water I still need to run the water pump..... am I missing something? oh, also, how do I get the outside TV to run on the cable hookup?
