"Low Battery Voltage" warning while cranking

I just bought a 2018 Thor Aria 3401. Being 4 years old I replaced the chassis batteries and the previous owner had recently replaced the house batteries. I have noticed that if I start the coach after it has recently been run I get a "Low Battery Voltage" message on the dash. The battery voltage when stopped is 12.7 or so and running is over 14 volts. I am told that this is a common occurrence while cranking and don't worry about it.

Do those of you with diesel pushers experience this? Thanks for your insite.

Perfectly normal

Grid heater pulls a lot of amps

Should clear in a couple minutes

My coach does the same thing every time I start it. Cranks and starts just fine.

I have an Aria 3401 too: Normal, diesel take a lot. My Ford 250 pickup even has 2 batteries.
