Rv ready for spring & summer?
 

Here are the top 10 items we recommend to make your camping season fun and safe for you and your family:
 
1.   Make sure you have your tool kit and safety items ready for the season. Some tips to carry are duct tape, wire ties, bulbs for the rv, the right fuses, a first aid kit, triangle flares, the right tools to work with your rv and maps and a GPS.  We always bring maps even if we have the GPS.
 
2.   Check your tires for proper pressure, wear, tread and age.  Tire companies recommend tires should be within 5 years and all tires are dated.
 
3.   Check all clearance lights, taillights and brakes.  If you have a trailer it is recommended you pack the bearings and do a physical inspection every year.
 
4.   Open your awning and make sure it is in good operating condition with no tears in the vinyl.  Silicone spray can be used on the awning arms to help with the function.
 
5.   Check the roof.  Make sure it is overall clean with no visible tears or damage, closely looking at the vents and skylights if any.
 
6.   Sanitize your fresh water system (see article on website). Also check for water leaks and make sure your pump works. Add some toilet chemical to your holding with a little water. Make sure your sewer hose and fitting are in good condition with NO leaks.
 
7.  Check your batteries.  Make sure they are fully charged and if they are “wet” batteries check the water level and fill with distilled water if necessary.  Make sure you do not overfill the batteries.
 
8.   Going inside the RV, check the filter on your air conditioner  if it is a roof mount unit.  Also check the bolts to make sure they are tight.  These are located under the white ceiling shroud.
 
9.   Check all appliances and make sure they come on and do what they need to do. Now is the time to flush your hot water heater and make sure your refrigerator cools down and your furnace heats up.
 
10.  Check your propane and make sure you have plenty.  It is also recommended that you do a propane safety test each year. You should also have the proper propane , co and smoke detectors.  Any detector over 5 years old should be replaced. 
 
Any questions on how to do any of these maintenance items, just drop us a line.  We are here to help and can be reached by telephone or email

                           TYPES OF RV ROOFS
  • Rubber/ EDPM Roof
  • Fiberglass
  • Metal
  • Plastic/ Vinyl
Find out what your roof is made of to give it proper care.
Below are care instructions for one of the most common and sensitive types of roof –
         The rubber /EDPM roof
                            “CARE AND MAINTENANCE” – from DICOR
The care and maintenance of your Brite-Ply roof is simple and requires no special materials.
  1. Annual inspection of the roof is suggested. Check the membrane for possible damage and check the lap sealant used in all termination areas and around all accessories & fasteners.

  2. Keep your roof clean. For normal cleaning, standard household products such as 409, 4U, Fantastic, or mild detergent is sufficient. Do not use harsh abrasives or products containing solvents. For stubborn stains, a rag dampened with mineral spirits is recommended. DO NOT SOAK.

  3. When cleaning, rinse thoroughly with clean water to avoid residue build-up on the roof or sidewall of the vehicle.

  4. Parking in areas where fruit tree sap may stay on the roof for extended periods of time may result in irremovable stains.
 
Carlisle’s Brite-Ply EDPM roofing membrane is specially formulated for exposure to the sun and natural elements. However, it can be cut or punctured by sharp objects. Use caution when placing any articles or walking on the roof. If damage does occur, the Brite-Ply membrane can easily be patched in the same fashion repairs are made to rubber inner tubes. Call your local dealer or DICOR for additional information.
 
CAUTION: DO NOT use cleaners or conditioners containing petroleum solvents, harsh abrasives, or
     citrus-based cleaners.
     DO NOT use mineral spirits in a large area or allow it to soak into the membrane.
            ROOF MOUNTED AIR CONDITIONER
Operates on 120 AC power or minimum of 2800-watt generator
Know the make/ model of your air conditioner and put the information on your component list
MAINTENANCE:
  • Filter should be checked/cleaned at least 3 times a year – located on the inside ceiling (excludes basement models)
 
  • Roof gasket should be visually inspected at least once a year
    -roof gasket should be no less than ½” thick

  • Roof bolts should be checked & tightened (if necessary) at least once a year

  • Have a tech check your drain holes, evaporator coils, and rear fins at least once a year.
                                AWNING CARE
Here is information on what the manufacturer of the awning companies recommends for care of the vinyl of your awning.
  • Open and inspect your awning at least twice a year
  • Silicone the arms and all metal moving part to prevent binding
  • After the rain, on a clear day open the awning to air it out to help prevent mildew and dirt from damaging the vinyl. Mildew forms on the dirt that has accumulated.

  • Wash with a non-caustic cleaner such as baby shampoo. Mildew remover or metal cleaner should not be used as they can destroy colors. This is not covered under warranty.
 
  • 303 Protector is the only product recommended. This protector can help enhance water proof-ness.
 
Awning Maintenance
  • Inspect the awning periodically, especially after bad/wet weather
  • Make sure all screws in brackets and rail are tight
  • Apply silicone lubricant to the threaded shafts of the black locking knobs and all sliding parts

  • Inspect the awning canopy for loose stitching and possible shrinking
 
Before traveling make sure the awning is securely closed and that you use Velcro awning straps for added protection while traveling.

Battery Troubleshooting and Maintenance



Specific Gravity
Measuring the specific gravity of the electrolyte generally checks the state of charge for a lead-acid cell. Specific gravity is a ratio comparing the weight of a substance with the weight of water. For instance, concentrated sulfuric acid is 1.835 times as heavy as water for the same volume. Therefore, its specific gravity is 1.835. The specific gravity of water is one, and therefore serves as a reference. In a fully charged cell, the mixture of sulfuric acid and water results in a specific gravity of 1.265 at room temperatures of 80°F (27°C). As the cell discharges, less acid is present and more water is formed, lowering the specific gravity. When the specific gravity is down to about 1.120, the cell is completely discharged.




Specific Gravity Readings
Specific gravity readings are taken with a battery hydrometer, such as the one shown. When checking the specific gravity, hold the hydrometer vertically so the float is not rubbing against the side of the barrel. Draw an amount of electrolyte into the barrel so that with the bulb fully expanded, the float will be lifted free, not touching the side, top or bottom stopper of the barrel. Your eye should be on a level with the surface of the liquid in the hydrometer barrel. Disregard the curvature of the liquid where the surface rises against the float stem and the barrel due to surface tension. A hydrometer reading of 1.265 indicates a fully charged battery. A 75% charge is 1.225. Approximately 1.190 is half-charged, 25% is 1.155 and 1.120 indicates complete discharge. Each cell of the battery should be checked. The readings for each cell should be approximately the same. If a reading of one or more cells is substantially different, it would be an indication that the cell(s) is bad. Make sure the hydrometer is clean and does not have any cracks. Never take a hydrometer reading right after you have added water or immediately after a charge. You will get a false indication. You must let the electrolyte stabilize for about 20 minutes. Never add electrolyte to a battery after the initial service. The chemical balance will be off and the battery won’t perform correctly. When adding water, distilled water should be used. Any mineral content could affect the chemical reaction and add to sulfation. The specific gravity will change as the temperature changes. You need to use a temperature compensated hydrometer to ensure accuracy.




DEEP CYCLE BATTERY MAINTENANCE
SAFETY
 Keep flames, sparks or metal objects away from batteries
 Always wear protective clothing, gloves and goggles when handling batteries
 Check that terminals are properly tightened; terminals that are too tight or too lose could result in post breakage, meltdown or fire


WATERING
 Add water, never acid, to cells (Distilled water recommended)
 DO NOT OVERWATER!
 If the batteries are fully charged add water to a level of 1/8” below bottom of fill well
 If the batteries are discharged add water to a level just above the plates


INSPECTION & CLEANING
 Keep batteries clean and dry from residue
 Check that all vent caps are tight
 Use a solution of baking soda and water to clean if there is acid residue on batteries or corrosion on the terminals
 Terminal protectors or protective spray should be applied to terminals to reduce corrosion


STORAGE
 Batteries should be fully charged prior to and during storage
 Never store discharged batteries
 Store batteries in a cool, dry place
 Recharge batteries before putting then back into service
