Is this the longest fifth wheel trailer?

By Chuck Woodbury

What do you think, is this the world’s longest fifth wheel trailer? How would you like to tow this baby? No tight turns for you, for sure.

Well, those questions are moot because we don’t think this is a real fifth wheeler at all but the product of someone’s imagination and photoshop skills.


The photo was passed along to us by reader George Bliss, who regularly alerts us to interesting things. He was told it had been built by Weekend Warrior and used by one of its owners. But after I asked him if he knew that for sure, he did a little checking. He then reported:

“After five calls to Weekend Warrior and finally speaking to the engineering department, I’m advised they only make three-axle RVs. They do not have a four-axle in production nor is one available through a custom build. It would seem to be a doctored photo but impressive all the same.”

So that’s what we know. If you know otherwise, please fill us in. And thanks, George, for the photo and research!

I expect that picture has been “Photoshopped” but, I have NO doubt that somebody has fantasized about building such a beast. In real world RVs, why would anyone build using FOUR axles when a dual tandem system will provide eight wheels and, is readily available (just about “off the shelf”)? The geometry of four axles along with the tire scuffing (typical with multi-axle builds) would be an engineering nightmare and, probably cost more too.

I have always thought of this as a funny answer to those folks who want to bring it all with them and the trend to make larger and longer rvs of all classes.

Forget the street corners. I want to see him back into the RV site that I’m in. That would draw a crowd.

That’s true…it would draw a crowd to watch him back into the site you are in!

If ever built, you would expect it to have a raised frame (approach and departure angles) so as to clear ramps and humps in the road or parking lots.

I have ask two questions related to all R/V. trailers. Why they cannot have underfloor storage compartments like motor homes, and why not put the A/C. units underneath the floor also like the ‘ALFA’ motor home series in the past so as the interior ceiling height could be increased and to reduce the air drag of the trailer when moving on the road?

Ask Mark Warmoth, the founder of Weekend Warrior. Since a bankruptcy auction in around 2009 many companies have used the name.

I only noticed two A/C units and only one vent on roof so thought it was a doctored up photo from the start. Also A/C units not spaced to effectively cool the unit.

Yes, because we all know that the one thing every RV manufacturer is concerned about is the cooling performance during the summer. I’ve never owned an RV that wasn’t like a meat locker inside during the July-August heat here in Texas…

That’s sarcasm in case you missed it.

If it makes you feel better it was 108 here in Florida yesterday. My hot flashes are having hot flashes

The indicator that it’s a doctored pic is the position of the axles, WAY far back. A real trailer would be more in-balance.

I think the indoor pool is aft of the wheels, so that would balance that long body ahead of the wheels.

70’ is maximum combined length on U.S. highways without an oversized permit which is expensive and requires an approved route to follow through each state, each state requires an oversized permit which would be expensive for the average RVer.

Spacecraft RV is a custom builder… Their website posts floor plans of 51′ + in length. There is a separate article showing a 59′ rig.

Even though you can possible get a rig like this (if you can afford it), there are many States that you can’t take it thru. Read more on that here:

Know the rules of the road before committing to something like that!

Aha! Somebody knew the right answer, Read the regs for a big rig. While some states allow more ………………… for example, this state allows Supertrains. That’s two full length trailers (52 feet each, with one being towed on a dolly in back to boot), you have to take note that states like California still adhere to the 65 foot total length guideline from years ago. And then there are those states that allow road trains.

This begs the question; “what is the maximum legal length that DOT will allow for any trailer?” Not combined length but length just for a single trailer regardless of what is pulling it. Any ideas? This does not pertain to doubles and triples as that is again “combined” length.

The maximum standard length for an over-the-road freight trailer is 53 feet, which taken with the typical length of a sleeper cab tractor, complies with maximum vehicle length. Nobody in their right mind would want a 5th-wheel camper trailer that length; it takes considerable time and training to nurse a 53-foot trailer around city street corners. There was a brief moment when Freightliner was lobbying for a 58-foot freight trailer, and they went so far as to build a stubby cabover tractor called the “Odyssey” to pull it and stay within overall length limits. The tractors sold; the trailers never did.
