Will i get up in the morning with dead batteries? No they will not be dead. Yes it's better to have match size but it's not the end of the world. The 975 is probably the one rated 135 AH... it alone will run just the refer all day. Your engine batter should be separate and not able to be used to run the refer.
Do a test by unhooking one of the two house batteries and measure the voltage. When it gets to 12.0 it time to charge it.
