Generator Prep is an option on some of Heartland's products. Not sure about the Sundance. If it is an option on Sundance, you will only have it if the dealer ordered it that way.
Sundance does not include a battery from Heartland. Your dealer will supply this. They usually supply a single 12 volt flooded cell deep cycle battery.
Nearly all the electrical items in your RV (lighting, furnace, water pump, vent fans, electric front jacks, electric rear stabilizers, TV antenna amplifier etc.) are 12 volts DC powered. When you are not connected to shore power at a campground, these items are powered by the house battery in your RV. When you are plugged into shore power, the converter in your RV will supply the DC power for these items and will provide a charging circuit for your battery. This is all automatic and other than inclusion of the battery - all standard.
There are a few items in your Sundance that are soley powered by 110 volts AC power. A few of these are:
- Water heater when used in AC power mode versus LP gas
- Refrigerator when used in Auto mode versus LP gas
- Air Conditioner(s)
- Track lighting (if so equipped)
- Fireplace (if so equipped)
- Tank heating pads (if so equipped)
- Clothes washer/dryer (if so equipped)
- Microwave oven
