NOT a Moron at all

On gas heat I get the red fault light, but no warm water.
On elec heat I get no warm water.
Becker to ensure both showers are not in bypass or mixing cold/hot.
And when holding the hot PEX line it’s seeming the same temp as inbound cold line.
Finally outside the switch is currently ok but doesn’t seem to make any difference.
Suggestions??? Thanks!!

You Are NOT a Moron. At least you know it is a Water Heater, not a Hot Water Heater.
There is no need to have a heater to heat Hot Water is there?

thanks, i guess that makes sense since there's no expansion tank. I'll make sure to not fully purge it!

It took several trips to realize the electric is slow to come on.
We traveled several times. I turned the electric side of the water heater on. Felt the case a little while later. Nothing! Panic time. The DW is tired and wants a shower.
Then started the what is wrong thing. The gas gets hot asap.
Takes an hour before the electric shows much signs of life!
The modern rv is getting to be a complicated beast.
The gas electric fridge is another steep learning curve!

It is funny but it is true. If you look at any set of house pans or RV plans the Water Hdater is labeled as "WH" There is no HWH on any plans.

Just as a general fact
To test the WH electric heat coil, turn off all power, an Ohm meter on each end of the coil will show continuity or all 0’s or no Resistance. Make sure power is off.

A proper functioning electric heating element in the Suburban water heater is now around the 10 Ohms range (the resistance is what makes the heat),as per their service manual we keep in the forum library
You do need to disconnect at least one of the electrical wires on the element to get the proper resistance value to it when checking with a multimeter. This video (although not for a RV water heater) will explain how to test electric water heater elements

What I meant was continuity tester. If it has continuity it is working. No continuity replace it.
