All systems go
Our countdown to the summer-long trip is into the single digits now, and so it is time to run the “Airstream systems check.” This is a routine that I started integrating to our pre-trip prep about a year ago, after we had to cancel a long-awaited trip because the brake actuator died while the Airstream was stored.
Although that situation was sort of a fluke (the actuator was part of a run of bad units that were later recalled), it demonstrated that we can’t take our Airstream for granted. It is almost nine years old now, and has seen heavy use. This spring I’ve been going through the areas of the rig that have shown wear. Through a process of refurbishing, repairing, and updating it has been put back into good shape, better in some ways than it has ever been.
In addition to all the stuff I’ve blogged, a few smaller projects got done in the past week. For example, I added LED light strips to the under-bed area. These turn on automatically when the bed is lifted, thanks to a magnetic switch. It was a surprisingly painful job, because I had to squeeze myself into the front storage compartment to connect wires, but worthwhile because before we never could see well when rummaging around in that storage area.
While moving the backup camera I discovered a second main ground wire, hidden inside the rear bumper compartment. This one was also somewhat corroded, despite being a bit more protected, so for good measure I disconnected it and cleaned it up as I had the front one. I also lubed all the locks and hinges with graphite, replaced the two big zerk fittings on the Hensley (they have special spring-loaded plungers that tend to wear off), replaced a bad cabinet spring latch, and other such simple stuff.
Since we’ve fiddled with the flooring, furniture, plumbing, windows, antennas, camera, hitch, belly pan, refrigerator, bathroom sink, and microwave in the past couple of months, it seemed especially important to do a good road test before we hitched up for the real thing. I recruited Mike, and we towed the Airstream down to the local highway truck stop, the TTT.
A good local truck stop can be a boon. At the TTT we were able to get months of desert dust and last summer’s bugs finally washed off the Airstream, then go around to the CAT scale to get weighed (and re-weighed after adjusting the weight distribution a little), and on the way there and back were had opportunities to check the brakes and dial in the hitch head adjustment on the Hensley. (This latter adjustment is crucial, as an off-center hitch head will cause the trailer to push the tow vehicle off-course in a hard braking maneuver. We only had to do this because we disassembled the hitch for painting, otherwise it’s a “set and forget” item.) If we’d been in the mood we could have topped up the diesel and had lunch at Omar’s Highway Chef, too.
Mike kept the ladies at the TTT front desk entertained while I went through the CAT scale. The report told me that the Airstream was lighter than it has ever been when loaded for travel with full water, at about 7,260 pounds. It has run as high as 7,800 pounds, but usually less. We haven’t yet finished loading some of our stuff, so when we leave it will probably be right around 7400-7450, which is fine.
While we were at the TTT I had a chance to walk around and inspect the tires, see if anything came loose (especially things I fixed!), and adjust the strut jacks on the hitch to move a little more weight to the front axle. I went around for a second weigh and verified that the tweak moved another 60 pounds forward. (By the way, our hitch weight came out to 660 pounds, or 9%. People often assume it’s much higher because of the size of the trailer, but it has always been around 9-11%, verified over the years by truck scales.)
The road test to and from the TTT verified that the new position of the backup camera is awesome. With the high mounted position I now have a clear birds-eye view of the traffic situation behind us—three lanes wide. I’m going to really like that when we get into heavy traffic situations like Dallas/Ft Worth. It’s also more useful when backing into the carport.
The test tow was about 40 miles roundtrip and it verified that everything seems tight, right, and ready to go. No surprises. Even the new cellular antenna clears the carport entry as planned. And it’s shiny again. So all systems are “go” for launch. We just need to get the crew on board and that should happen by the end of the week.
