Dummies Guide for a Class B

Yep, I had to do it. I needed to get my thoughts together to figure out how this darn Class B motorhome works. So I created my own Dummies guide along with a checklist. Not sure if it is accurate but it allowed me to ask my husband how things worked and document it for myself.

Note: This is particular to the Leisure Travel Van Free Spirit – 2006/2007.

Dummies Guide for the Free Spirit

Free Spirit Specs:
Fuel Tank – 26 gallons
Fresh Water Tank – 26 gallons
Grey Water Tank – 21 gallons
Black Water Tank – 9.8 gallons
Hot Water Tank – 6 gallons
Propane Tank – 11.5 gallons (can only fill to 85%)

Types of Power
1) Engine Power (Vehicle Battery and vehicle alternator) – 12-volt DC
2) Coach Power (2 deep cycle batteries parallel approx 250 amps) – 12-volt DC
3) Shore Power (usually 30amps but can be 15, 20 or 50 amps and 120-volt AC) – Most parks have 30 and 50 amp for you to choose from. Need adapters for each. Our cable is for 30amp.
4) LP tank
5) Generator

1) Engine Power (recharges while driving)
Windshield wipers
Cab heat/air conditioning
Dashboard lights
Radio/CD/DVD Player – if engine switch selected on dashboard
Power doors, mirrors, locks
Cigarette lighter (for Garmin)
*Charges both vehicle battery and coach batteries while driving

2) Coach Power (recharges while driving)
Interior Lights
Exterior Lights
Water Pump
Furnace (fan and controls)
Shower fan
Roof vent fan
Alarm systems (LP and CO leak detectors)
Radio/CD/DVD player – if coach switch selected on dashboard
Monitor panel
TV Antenna booster
12 volt appliances
TV (120 volt) but use with inverter to make it run on 12-volt – always powered by coach battery
Refrigerator – 3 way – Coach Power, Shore Power, LP tank (most efficient)
*coach batteries will eventually run out – nothing is charging them

3) Shore Power
Everything on coach power
Air conditioner/heat pump
Microwave oven
Hair dryer
Coffee maker
Refrigerator – 3 way – Coach Power, Shore Power, LP tank (most efficient)
Anything that plugs into a typical house receptacle
*Charges coach batteries while plugged into shore power (but not vehicle battery)

4) LP Tank – 11.5 gallons – need to refill at fuel stations
Refrigerator – 3 way – Coach Power, Shore Power, LP tank (most efficient)
Furnace heat

5) Generator (2800 watt or 2.8k watt) – Propane powered from LP tank
Supplies 120-volt power into RV
Charges coach batteries while running (but not vehicle battery)
An alternator is an electrical generator which generates alternating current.
A converter transforms 120-volt AC into usable 12-volt DC electricity.
An inverter turns 12-volt DC into 120-volt AC power.
Watts / volts = amps
Amps x volts = watts
Typical usage of 12-Volt items
Lamp bulb – 2 amps
Water pump – 5 to 8 amps
Air conditioner – 2,000 watts
19-in TV – 30 watts
Coffee maker – 1000 watts
Microwave – 900 watts
Furnace – 5 to 8 amps
Stereo – 50 watts
Electric kettle – 1500 watts
Fridge – 18 amps
