These things are a Menace, John

Sometimes we feel like we grew up on the road. Our parents would hit the road for a weekend or plan a road-trip vacation at the drop of a road atlas. We've spent a lot of time on a lot of great North American roads. We've logged thousands of family miles, thousands of solo miles, and thousands of companion miles. We've driven and/or owned hatchbacks, wagons, SUVs, and pick-ups -- stick and automatic. We're no experts in highway safety; however, we've seen enough things to give us plenty to think about, especially during those stimulating stretches of topographically-diverse Nebraska.
For the past few years, we've gotten to thinking about safety and the road just around every Memorial Day weekend. In simpler times, it used to be that we celebrated the sacrifices of our veterans through a paid holiday, lowering the flag to half-staff until Noon, barbeques, and drunken boating. These days, however, things are more complex for we live in troubling, uncertain, and dangerous times. In addition to its patriotic duties, Memorial Day serves as the "official" beginning of the summer driving and vacation season. Not coincidentally, it is also the time that the two greatest dangers to the American road traveler break their winter dormancy: the slide-in, pick-up bed camper and the fifth-wheel trailer on tiny wheels. Like parasites, they attach and attack "[hu]mans' best friend", the automobile.
John, they not only compromise our vehicles but they put us at risk too.
Let's review quickly. Fifth-wheel trailers attach to the truck inside the bed using a fifth-wheel hitch similar to that seen on heavy semis. These hitches have numerous advantages over trailers attaching at the back via a ball hitch, making their grasp on their host that much more tenacious. Aside from their deadly grip on a truck's behind, they are easy to spot in that they possess tiny wheels --and this is the key to their destructive power.

The first problem is the large amount of weight placed on such little tires. Furthermore, furnishing and outfitting the trailer adds more weight. Also, it seems that there are a lot of really crappy tires out there.
The other problem is that the infected tow vehicle, on relatively large tires, can drive insanely fast. The trailer's smaller tires, on the other hand, have to spin much faster to maintain that speed. Speed leads to heat; heat expands the air inside tires; tires blow up. We've seen plenty of colossal blow-outs at highway speeds ourselves. We've been several car-lengths behind when we have heard the pops, seen the shredded carcasses of tires, or tracked the trajectory of separated tread flying off onto the road. Contrast this with healthy semis who usually possess dual-wheels of the same size as their tow vehicle. When they lose a tire, the other one usually keeps the truck rolling to a safe stop. But when one of these single-wheels pops, the result is property damage to the host, traffic delays for the rest of us, and possibly much worse. We hate being anywhere near these things.
But more than that, we loathe the pick-up truck campers. The slide-in pick-up bed camper is not a camper shell (or truck cap), which is a perfectly noble organism that covers the pick-up's bed and keeps one's stuff protected from the elements. This is the difference between symbiont and parasite. The slide-in camper is a horrible structural tumor that slides into the bed and most frequently secures itself by a number of chains that reach down to hooks and beams under the truck's frame. We've noticed that the newer ones --the ones that aren't rusted, old, and with pieces of circa-1973 aluminum siding-- have been getting taller, wider, and longer. John, they are adapting to today's stronger trucks.
We love pick-ups, in fact they are our preferred class of vehicles. The last thing that we'd ever wish for them is crippled handling and safety. To begin with, slide-in campers raise a truck's center of gravity somewhere up into the mesosphere. Were that not bad enough, they're getting wider. For example, the growth (pictured at the top of this post) that we examined this weekend stretched comfortably at least a foot, on each side, beyond the truck's bed. Again, in healthy semis, the alert driver will notice that semi-trailers are about as wide as their track width (distance between left and right tires). With the truck above, picturing it from behind yields an inverted trapezoid of deadly weight ready to crush you.
Finally, in addition to the aforementioned safety feature of dual-wheels, the other feature of duals is increased stability against rolling. This is why truck camper attached to a single-wheeled host are all the more dangerous. It's like Andre the Giant on a unicycle... on a tightrope: unsafe at any speed. We can't wait but cautiously overtake one on the road and put it's bloated, top-heavy danger behind us.
Listen, Steinbeck, a lot has changed since 1960. Why do we insist on dressing up and rolling out Jed Clampett technology onto our roadways? When William Least Heat-Moon made his epic journey, he had the sensibility to drive a van and improvise to meet his needs. Our need to bring everything-including-the-kitchen-sink, while endangering other drivers, in order to enjoy our RV Freedom will surely lead us down the path to ruin and topple us from the mantle of the Greatest Nation Ever.
