Dave shows off his new purchase, a 1997 Salem that looks to be structurally sound, but which has a punchlist of systems and accessories that need to be inspected, tested and (probably) fixed before hitting the road.
Components such as the interior lights, roof vents, water pump and more are powered by a 12-volt deep cycle battery. This session covers the different types of batteries such as flooded lead acid (FLA), absorbed glass mat (AGM), and lithium. Other information includes how the converter charges the batteries, how to test the converter, and troubleshooting the 12-volt system.
Liquid propane (LP) is the fuel that provides power to the refrigerator, furnace, stovetop and oven, as well as the water heater. Travel trailers and fifth wheels have DOT cylinders, while motorhomes have horizontal ASME tanks. This session covers the different tanks, certification requirements, proper filling, and an overview of the operation of the LP system. You’ll also learn about checking for an LP leak and traveling with propane.
Fresh water can be provided by a pressurized outside source from the campground (known as “city water”) or by a freshwater tank and an on-board pump. In this session we provide an overview of how the system works, checking for leaks or non-working faucets, and how to fix an improperly installed water pump and a variety of leaks.
The wastewater system consists of two different tanks: the black water tank, which is for the toilet; and the gray water tank, which holds shower water. This session provides an overview of how the wastewater system is designed, proper treatment products and cleaning methods for each tank, and some tips to keep your monitor panel readings accurate. We also show how to install a new dump valve configuration and provide a tip to lubricate the valve lever.
Most RV owners take the roof air conditioner for granted — out of sight, out of mind. Not a lot of maintenance is required, but an occasional inspection will help the unit run more efficiently. It is important to understand how the roof air conditioner works and what it can and can not do. Cleaning filters, evaporator fins, and verifying airflow are also covered.
We knew our trailer had a water leak, just did not know the extent of the damage. After tearing into it, the damage to the sidewall and flooring was substantial, requiring new joists and flooring. It is important to check for leaks periodically and fix them before they can do this type of damage. This session shows how to perform a leak test and what to look for.

Very few people looking to purchase their first trailer buy something new, opting instead for a used unit that is much less expensive. According to recent surveys, over 50% of these buyers did not purchase their rig from a dealer but from a private owner through eBay, RV Trader, and other platform. This typically means there was not a very detailed walk around or pre-delivery inspection (PDI) for the new owners to become familiar with how things work or what they need for accessories.

It is important to become familiar with how every system works, what might not be working, and how to check and test components in order to make your RV experience much more enjoyable. More than half of the calls RV roadside assistance programs receive are due to owners’ not knowing how their systems work.

This class will provide information on recommended maintenance for the roof membrane and sealants, as well as the sidewall and decals.

You’ll want to check certain components to ensure proper operation and to prevent potential issues down the road. Learn about how to check the liquid propane (LP) system for leaks, for example, and proper filling of the containers.

Additional information covers how to verify all appliances such as roof air conditioners, furnace, and refrigerator are operating properly.

And finally, you’ll see how to test your rig for one of the “gremlins” of RV’ing: a water leak that will not become apparent until the damage is already done.
