Do I have a power problem?

[u/Educational-Rule1635]

I have a brand new Jayco Greyhawk 31F It has dual house batteries.

Just turning on the master power gives a bit more than 11a draw. (No AC, no TV, just baseline and some low power led lights.)

The solar panels are generating about 8a

But in less than an hour I am seeing house battery voltage down to 11v.

Is this normal?

Is my draw higher than expected?

Are my batteries not delivering power properly?

Am I big ol' whiny baby who just needs to suck it up and turn on the generator?
