Wash and wax, tricks and treats

Salt deposits had been washed off our Airstream Safari trailer just after we returned home from our last beach outing, and now it was time for our big annual wash and wax job prior to the beginning of our fall camping season.  The trick is to use a good quality wax that is easy to wipe on and off, and provides long lasting protection.  This is the eighth year that I have used Meguiar’s M20 Mirror Glaze® Polymer Sealant to wax the trailer and I have been treated with its ease of use, high gloss finish that makes it easier to rinse off dirt between washings, and its ability to prevent and/or control filiform corrosion.  The 16 oz. size nicely covers our entire 23′ trailer, including the roof and air conditioner shroud.  The trick is to get it on the roof, and I have a crutch for that, literally.

This year, sun safety for my skin was provided by my wide brim plague doctor’s hat, and for a brief moment by a calavera mask, a calaca, a skull mask, often used in celebrating Día de los Muertos* (Day of the Dead).

For us, this season is also a reflective time for reviewing the past year’s events, the tricks and treats.  For example, last November our corgi, Tasha, had a herniated disc, and the trick was to find it with an MRI and to remedy it with a laminectomy, and the treat was that she went on to a full recovery.  Last June, we found the trick on how to stop paying $75/month for cable TV channels that we mostly don’t watch, and now we are treated to free TV by using an indoor antenna.  Last August, we found the trick on how to stop paying high prices for cell phone service that we rarely need, and we treated our selves to a new service provider, resulting in better service at much lower prices.  In August, we were also treated to the happy sight of our first pitahaya blooms, and last month, we were treated to the sight of our first fruit after bees and I (with a brush) performed the trick of cross-pollination.

Safari shine on harvest moon

Washing the dirt and salt deposits off our awnings after the trip to the beach was the prelude to our annual big wash and wax job before the start of our fall camping season.  Over time dirt and salt deposits can weaken the awning fabric and shorten the functional life of trailer awnings.  See Zip Dee’s video, “Cleaning Your Zip Dee Awning Fabric“.*

A fabric bead strip attaches the awning to the trailer via the awning rail…

and when the awning is closed, this strip forms a trough that collects and traps dirt.

I am always amazed how much dirt is flushed away when I extend and wash the awnings.

Our fall camping prep continued with a midsummer cleaning and repacking of our Safari’s wheel bearings and having the brakes adjusted.  Last week as the Harvest Moon rose*, we ate Moon Cakes in celebration of the Chinese Moon Festival, also known as the Mid-Autumn Festival.  Cool, fall weather arrived just in time for my big wash and wax job of the entire Safari trailer, including the roof (white wax dust particles are seen in the photo above).

I washed our trailer with Meguiar’s Deep Crystal Car Wash and on the following day I sprayed Boeshield T-9 on any areas of aluminum that had first shown signs of filiform corrosion (that was stopped in its tracks years ago by this product).  Only a light coating is needed (spray on and wipe off before it dries) as this product penetrates any breaks in the clear-coated aluminum and helps to block salts and oxygen from corroding exposed aluminum.  I then applied my favorite wax, Meguiar’s Mirror Glaze Professional Polymer Sealant #20 (the dry residue easily wipes off and the protection lasts over a year).  I then applied 303 Aerospace Protectant to the rubber seals of the Fan-Tastic Fan and windows and doors (keeps them from sticking and prevents UV damage).

Leaves are starting to fall from our Ginkgo tree and the nights are now cooler as we anticipate our early October return to the Cuyamaca Mountains.

It was a bit of work, but by using quality protectants annually this nearly seven-year old Safari still shines and is ready to resist the elements, which makes me smile and want to sing and dance!*

Getting my bearings…

We were first time RV owners when we picked up our brand new 2007 Airstream Safari, six years ago, so from the start, I tried to get my bearings on its operation, function, and care by reading the Owners Manual.  I found much of the information to be useful and valuable, but some of the service schedule guidelines did not seem practical to me, such as “Every 10,000 miles or 6 months – Inspect, adjust, or replace brakes as necessary [and] Clean and repack wheel bearings”.  I understand that now Airstream recommends every 10,000 miles or one year for the above items.

I have read that one reason to repack bearings* every year is that condensation can occur in the hub and cause deterioration of the grease.  But some say, “If you live in the dry Southwest, you can probably go 2-3 years between repacks.”  Even though our Airstream has only accumulated 9,500 miles (and stayed in San Diego County), I knew we were overdue for the first repacking of our bearings, so when I read the recent AirForums’ thread, “Bearings went bad and hub is damaged“, I was motivated to take action.

After reading the 14 steps of  “Wheel Bearing Maintenance” in the Owners Manual, ’77 Overlander’s “Bearing Repacking” guidelines, “Bryan and Dave’s Greasy Adventure“, and watching, “How to Repack/Grease Trailer Wheel Bearings“*, I realized that this is a science and art beyond my capabilities and tools.  I found excellent reviews of a local RV mobile serviceman, Abe Hernandez of RV Mobile Service 2U, and made the appointment.  I found him to be positive, knowledgeable, and eager to share his knowledge and experience. He allowed me to take photos and thoroughly answered my questions.  First, he showed me where our Airstream’s jack points are located, as mentioned in the Owners Manual, a label with the word “JACK” in blue letters and an arrow points to the jack point, a 3″ square plate riveted to the mainframe rail.

Tools and supplies included an aluminum service jack and smaller jack stands, dust cap remover, seal puller, bearing cleaner supplies, bearing packing tool, Diamond Grip latex gloves, new seals, new cotter pins, seal driver, hammer, various pliers, tire wrench and torque wrench.

The brakes were cleaned with NAPA Brake Cleaner, and inspected and adjusted.

The bearings were cleaned and repacked with high temperature red grease.

New seals were installed.

The wheels were reassembled with special care to ensure that the spindle nut (castle nut) was not over tightened.

So now I’ve got my bearings and hopefully, for some time down the road, they will be easy riders!*

Aye, there’s the rub rail

A rub rail covers the bottom edge of the exterior aluminum panels, along with the bottom line of rivets that attach the panels to our 2007 Safari trailer.  This rub rail area is susceptible to water in at least two places, especially in the rear of the trailer where much rain water and dew run down.  The trailer was only two years old when we found part of the chrome/vinyl rub rail insert hanging down during a trip.  Moisture can loosen the self-sticking adhesive backing of this vinyl insert.  We reattached this vinyl strip using 3M Plastic and Emblem Adhesive #08061 and details are posted here.

Click on the image above to enlarge it and you will see that the factory applied sealant along the top edge of the rub rail bracket.  The integrity of this seal is important, because if enough water gets behind the rub rail it could lead to floor rot.

Last summer, I found areas of cracked sealant along the top edge of our rub rail.  In one respect, we are fortunate to have a relatively dry climate in San Diego, but we do get plenty of dew.  So after I replaced our Marathon tires in September, I sealed the rub rail cracks with Acryl-R and applicator from the Airstream Store.

Actually, I put a bead of Acryl-R along the top edge of the rub rail around the trailer, and then the trailer got its annual big washing and waxing.  For the occasion, I got a new, sturdier stepladder and more of my favorite wax, Meguiar’s Mirror Glaze Professional Sealant #20.  This sealant, along with the nail polish that I applied last year, has prevented any further growth of filiform corrosion.

So now that the trailer is washed and waxed, and presented with new tires (and new AGM batteries last May) it seems happier and ready for our fall camping season. We celebrated by observing the Chinese Moon Festival, also called Mid-Autumn Festival.

Larry set up a display featuring the many symbols of this festival, including mooncakes with an egg yolk in the middle.

We gazed at the full moon as our Chinese paper lanterns seemed to dance, and the Tillandsia secunda (in the foreground) seemed to wave in the breeze, and we remembered the legend of Chang’e, the Chinese goddess who lives on the moon, a love story.

A marathon experience

Our Marathon tires became six years old (from date of manufacture) during our summer of ’12 and we knew that, even though they looked OK, they were already beyond the expected lifespan of a normal trailer tire and needed changing.  The tires that came with our newly built 2007 23′ Airstream Safari trailer (Goodyear Marathon ST215/75R14) have served us well and have had no problems with our routine of going on monthly 200 mile round-trips, mostly from San Diego to our nearby desert areas, from October through April, and one last trip of the season to a nearby state beach in May.  In addition, I make sure they are at the specified pressure of 50 psi cold just before starting and I monitor them with PressurePro tire sensors. When the trailer is parked, the tires are immediately covered (sun protection). We typically travel at the posted speed limit for vehicles towing trailers in California (55 mph) and rarely go over 62 mph. Upon return to San Diego, our trailer and tires rest on plywood boards placed on top of the cement pavement and the tires are covered.  So, even though there is much discussion about tires and tires sizes on the forums, we chose to replace our tires with another set of Marathons!

I obtained our 5 tires locally from SD Tire and Wheel Outlet, used a 4-arm lug wrench to loosen the lug nuts, and used the F-250’s tire jack to raise the trailer.

I was surprised to see the curbside hub dust cap covers (aka grease caps) were not attached, but just inside the exterior hub cap!  They could have come off during a trip, or might never have been properly installed at the factory, but the visible area of the end of the hub looked clean, so the dust caps were installed with the help of Larry holding a board while I tapped with a small sledgehammer.

The street-side grease caps were in place as expected.  So all tires were replaced with recently manufactured Marathon tires, including the never-used spare tire.  A torque wrench was used to tighten the lug nuts, and will be used to recheck them at intervals on our first trip out to the desert.

I decided against the added expense of Centramatic Balancers for these 14″ wheels based on how we use our trailer and how our tires showed no uneven wear in over five years.  And the rubber valve stems never gave us a problem with our tires (maximum pressure cold of 50 psi), but I do like the new ones on our new tires with the metal tips.

Putting on five new round tires is a perfect way to start our fall camping season and the first of the new year celebrations that we enjoy observing, in this case, with a delicious round challah (a sweet egg bread) that Larry made with Craisins.

Roundness and sweetness are perfect symbols for the start of Rosh Hashanah, along with the apple that is sliced, and dipped in honey!
