I am camped next to a motor home that is having HW issues and I am trying to help him... The HW heater is a Suburban gas / electric / auto ignition model that until yeaterday has gone dead... It will...

The Suburbans have separate systems for 120 and LP heating.
I would start with one system and work through that problem.
LP:
Check to see if 12 volts DC is getting to and from the switch.
If getting to the switch check for the 12 volts getting to the circuit board. The ECO or thermostat could be open preventing this from happening.
If power and ground are getting to the circuit board listen for the ignitor to operate. Power and no ignitor, time for a Dinosaur Electronics circuit board.
120 volt AC: Many have two switches the one inside the rig and a service switch on the outside access. Carefully verify whether 120 volts AC is getting to the element side of the switch. Check to see if the reset on the thermostat is good.
Many possibilities on each system.
