2nd battery
I just purchased a 2017 Thor 29FE. I noticed that there is only one 12V house battery. But, there's room beside it for a 2nd battery. My previous Class A had 2 batteries. Is it advisable to put the 2n...

Current flow is rated in amps. Battery charge capacity is rated in amp-hours. That is Current X Time. A 10 minute shower for a 7.5A pump is 10/60 hours X 7.5A = 1.25 Amp-Hours.
If you want to get into energy, that is Current X Voltage X Time = Watt-Hours, or for your home and electric bill, kilowatt-hours. Which is also equivalent to Joules. 1 Watt-Hour = 3600 Joules.
Here is an example pump that has a current rating of 7.5A.

The pump is of course used any time you use any water, and a big user is flushing the toilet. We have 40 gallon gray and 40 gallon black tanks so may find us toting water after a few days to refill our 40 gallon fresh tank.
We try to minimize our battery usage during dry camping and have all LED lighting. Battery life is directly related to depth of discharge, greater depth of discharge = fewer recharge cycles.
