Airstreams are built to last, well that is what is generally understood, but there are quite a few threads discussing how their frames/chassis rot with time. So I decided to have mine professionally rustproofed, as we have been doing for decades with all our vehicles in this part of the continent.
I was under my trailer, preparing it to be pressure sprayed with the oil/resin formula which penetrates all the nooks and crannies (such as between the belly pan aluminum sheeting and the steel frame, a source of corrosion) and then thickens to a tacky molasses consistency for durability. I happened to glance sideways over to the trailer (an SOB) parked next to mine in the RV storage compound; the axel/suspension seemed familiar. Curious, I crawled under to take a look, and sure enough it was our familiar Dexter system, pretty neat. But then my jaw dropped, the whole undercarriage of the trailer was solid aluminum (see photos), including the sub floor structure. This was a 2013, 23’ Camplite trailer and there wasn’t a speck of rust or corrosion anywhere to be found (except on the steel Dexter axel and suspension parts). I took a look on their website to see how they were built:
Is this manufacturer “out airstreaming” Airstream? Imagine a trailer where you don’t need to worry about corrosion forever! Sure they don’t have the iconic Airstream design (Avion tried that a few decades ago), but if one is intending to pass on their prized possession to their kids, or ensuring that it maintains its value, or looking at acquiring a more vintage model without having to remove the shell and repair or replace the whole frame as many have and are doing, such built-in quality is certainly a selling point.
Does anyone know if Airstream ever considered going all-in with aluminum for a truly long-lasting high-end travel trailer?
