This 1950 "M" System Trailer Is the Surprise Restomod You Didn't Know You Needed Today

This travel trailer has double the dose of strong personality because it retains the exterior of a classic and combines it with an interior that could be described as a restomod. The unlikely combination, the rarity of the trailer, and the low asking price have turned the unit into somewhat of a viral star.

Even if you're not on the market for a new family RV, it's worth a couple of minutes of your time. Everybody must love a viral star, right?

This is a 1950 "M" System trailer, described by its seller as a super-rare unit. The seller isn't fibbing, either: only a handful of these trailers have been known to survive, even though production must have been considerable given that the company operated for more than two decades and once boasted of making the most popular travel trailer in North America.

"M" System started out in Vicksburg, Mississippi in 1935, with smaller trailers that aimed for affordable luxury – as much as that was possible in a compact footprint. For the first 15 years, founder Joe Bonelli also built the trailers with lengths between 18.5 feet and 30 feet (5.6 meters and 9.1 meters).

According to one media outlet, the highlight of these towables was the lightweight tongues that allowed towing with daily drivers while offering the creature comforts of a home.

In the following decade, "M" System trailers went for a new design language, while expanding in size. By the late '40s, they included Hollywood windows and Art Deco exterior styling, and perhaps just as importantly, a wet bath. The bathroom was small enough to allow you to use the toilet, brush your teeth, and take a shower all at the same time, but it surely beat having none at all.

Production of the "M" System trailer continued throughout the '50s, but the offer catered mostly to the luxury market. Units were now as long as 50 feet (15.2 meters), offering up to three bedrooms and full kitchens; more than just vacation homes, they were now proper mobile homes – offered at triple the price of a house, as per the same outlet.

The company slipped off the radar at the end of that decade, and through the years, only a few examples have emerged on the used market. This is one of those rare times. Count yourself lucky because what you're seeing is the RV equivalent of a unicorn, even if you won't even consider buying it.

This is a 1950 "M" System trailer, possibly the 25.5-foot (7.7-meter) single-axle Special Deluxe model, redone in a way that shocks for the contrast it creates. While the trailer retains the Art Deco exterior, down to the Hollywood windows, the interior is much like what you'd see in a log cabin.

If you look closely, though, you'll notice some changes right away, on the outside. One of the access doors is blocked, and at least two windows are boarded up. The seller doesn't offer an explanation for either.

The interior is all wood, from the cabinets to the walls, floor, and ceiling. The layout seems to be the original one, so you still get a cozy lounge, now equipped with what looks like a fireplace and a home office where you can get some work done, a main bedroom, a kitchen, and the remains of a bathroom.

The listing describes the interior as "cozy eclectic," which is perhaps an accurate description of the living room of all grandmas in the world because that's the other strong vibe coming from the RV: grandma's home. Think not flowered patterns but rather heavy furniture combined with plush sofas. It's not a bad look, if that's your thing.

More modern features include a vintage-style fridge in the kitchen, a microwave, a two-burner electric hotplate, and a detachable faucet sink. A 5,000 BTU AC unit has been added recently, while the electric fireplace doubles as heating. There is no hot water, and whatever shower you take outside will have to be with cold water. The former wet bath has now been turned into a closet space with a Porta-Potty, probably to get rid of the holding tank and shave off some weight.

Elsewhere, you get plenty of storage options and, as noted above, enough space to get some work done, if you're a very modern (wo)man who never really takes a day off, even on vacation.

The listing notes that the trailer "pulls great," having just traveled from South Carolina to Florida "with no problems." This "not perfect but perfectly unique" RV is asking $25,000 and comes with a clean title and, perhaps more to the point, a novelty status you wouldn't get with any other towable.
