Another tip for any RV that helps to extend coach battery life between charges when camping without hookups (that was also mentioned way earlier in this discussion) is to power as many electrical items as possible directly off 12V instead of using inverters to power electrical items off 120V AC ... as inverters are not 100% efficient - and hence waste coach battery energy.
We now use such things as:
1. All 12V fans for warm weather ventilation.
2. A laptop that is charged using a 12V brick for it that plugs directly into cigarette lighter receptacles in the coach.
3. 12V brick chargers for our phones that plug directly into cigarette lighter receptacles in the coach.
4. A 12V brick charger for a CPAP machine that plugs directly into cigarette lighter receptacles in the coach.
Checkout this website to get an idea of what appliances can be powered by 12 volts from the coach battery system in an RV when drycamping:
