How long is a string?Hey all you long timers: How many batteries is normal for the house?
Seriously, the "typical" new RV battery bank(s) varies widely with the RV size, cost, and intended usage. And motorhomes have both house and chassis batteries.
Small motorhomes have at least one house battery but two is probably more common in the mid-size models. Larger or more upscale models have anywhere from 4 to 8, but the count gets confusing because sometimes they use larger physical size & capacity batteries [such as a 4D or 8D] but fewer of them.
You really need to measure batteries in terms of capacity, either amp-hours (AH) or reserve capacity (RC) minutes. That "one battery" might be anywhere from 75-115 AH.
