 The easiest thing to try would be a new temperature sender in the engine.I have no idea where it would be or what kind you would need because of it being a motorhome.You could go to an auto parts and purchase a mechanical coolant temp gauge and install it and get an accurate reading instead of an "idiot"light.

 You have 2 senders then so either you changed the wrong one or the wire from the light sending unit is shorted to ground or the circuit in the dash is shorted to ground somehow.

 Yes I do think there are 2 senders you will have to look around in the block or cylinder head to try and find it.
