House batteries not up to ah rating
Bought 2 new Interstate SRM-24 group 24 RV/Marine batteries a few months ago. I have used the MH 4 times on trips lasting from 3-6 days. Never going below 40 amps before recharging. The rating is 85...

85 must be a 100 hour rate. Real world closer to 75 AFAIK.
Per Interstate's spec the 5A load capability is 17 Hr for this battery. That is 85 AH at greater than the 20hour load.
FYI for what it is worth, a Trojan SCS 150 GR24 is rated at 100 AH @ the 20 hr rate.
