Question: How long should my battery last?
Answer: This is a common question for new trailer owners. Deep Cycle Marine Batteries (like the one supplied on your camper) are rated by size or "amp hours". Typically, group 27 batteries hold approximately 115 amp hours of power. This means that when fully charged, it should power the average RV furnace for approximately 30 hours of operation. Running TV's, lights, water pumps, water heater, ignitions, refrigerator controls, etc...All contribute to weakening your battery faster. A good rule of thumb is that a large travel trailer equipped with two Deep Cycle batteries, should power the camper for an average weekend of use. Smaller trailers like expandables (trailers with tent ends), can get the same results with one battery.


Question: How long should I charge my battery?
Answer: This question has many variables like size and rating of the battery, and rating and type of battery charger. Let's take the most common application for a brief explanation. Let's say we have a group 27 Deep Cycle Battery (rated at 115 amp hours), and a battery charger that has a Deep Cycle setting of 2 amps per hour. If the battery is dead, be sure to maintain the battery by checking and filling the cells with distilled water. Next, at 2 amps per hour coming out of your charger, it will take 57.5 hours of charge time to fully charge your battery. So be patient and plan ahead. The most common appliance failure (furnace not lighting) is a result of under charged batteries. The amount of charge you put back in your battery while driving is relatively small (most vehicles produce under 2 amps per hour of driving). So don't rely on this as your source to recharge your batteries. Purchase a quality battery charger with a Deep Cycle setting


Question: My furnace will not light and blows cold air, what is going on?
Answer: 99 times out of 100 this problem is related to improperly maintained or discharged batteries. Your furnace uses 12 volt (battery) power to spin the fan. When your battery loses voltage, it spins the fan slower and slower. Eventually (around 11-12 volts) your battery cannot produce enough power to spin the furnace fan fast enough to safely light (most furnaces have this safety feature). The result is a cold night! Don't be fooled into believing that you can recharge your battery by starting your tow vehicle for a couple of hours. This puts a very small amount of charge out to your battery, and may only produce short term results. Proper maintenance and charging of your batteries is the only way to avoid this problem. You can check this by plugging your trailer into 110 volt power and testing the furnace. If is lights on 110 volt (12 volt power is generated through your converter), then your problem was battery related. Stop by and ask us for a battery brochure for more information.


Question: How and when do I winterize my trailer?
Answer: Winterizing your trailer is required anytime the outside air temperature is going to fall below freezing. Most water lines and tanks are plastic and will crack and be damaged if left with water in them in freezing temperatures.
To winterize your trailer, follow these steps...
1. Drain all your tanks (fresh water tank/black tank/grey tank/water heater).
2. By-pass your water heater (kits are included on most manufacturers).
3. Siphon RV antifreeze out of antifreeze bottle using your trailer's water pump (some manufacturers have already installed this kit. If not, this kit is available in our parts store).
4. Pump antifreeze through all water faucets and showers (toilet valve too). Do them one at a time ensuring that each water line is now full of antifreeze. Pour some antifreeze down each sink and shower drain (not necessary on toilet).
5. Remove the 12 volt battery and store inside where it will not freeze.
