M100/M416 width opinions wanted

Hello,

I’d like your feedback on ideal width for both the tub/body of the trailer and the track width. How do these small narrow trailers tow behind wide late model Jeeps, full size rigs, Toyotas etc?
Narrow body and narrow track width will work well in our local PNW tight trails but I’m thinking that’s about it. Rutted non technical trails and forest roads make me start thinking how important same or close track width to the tow vehicle would be much more stable with less opportunity for the trailer to get crossed up and flip as I seem to see quite often with these narrow M416 style trailers. then I think of driving 10 hours on the freeway at 70mph where these surfaces are also rutted or snow slush covered and I see that this would be somewhat sketchy or at least exhausting.

For those wondering what I’m up to…. I recently acquired a M100 trailer tub missing the floor (so all four sides only) that I am considering using to build up a new frame/suspension and it would be relatively easy to cut and add material to widen the trailer for a desired width. I was considering widening the tub 8” to be 56”(including round stock rails) and also between 62-65” track width to match my JK(65”) But am I ruining the appeal to this trailer by adding this width and really it’s not a bid deal so just leave it alone. That is really what I am trying to learn from this thread.
The M100 is 3” narrower at the bottom(38 vs 41”) and 4” narrower at the top (48” vs 52”) for a M416 So this adds a little to my concern. This compared to my M101 it is almost inconceivable that it would work well towed behind a JK, that said it is also hard to think one would tow the larger trailer as well.. however I have been quite pleased and have towed it across the state and up difficult trails to some pretty spectacular alpine lakes. Other than super tight trails this works great with the exception of weight. My JK pulls it fine and pretty much can’t tell it’s back there but over a long freeway drive up and down mountain passes in the summer heat it adds up and is a little taxing both on the wallet and is somewhat draining on the mental/physical side. I’m thinking going light weight and more capable might be the way and can shed 1000 or more pounds going the M100/416 route.

thank you for any insight!

My m416 trailer has been towed over 10,000 miles at interstate speeds up to triple digits. Mine has 1.5” wheel adapter spacers and 17x9 “0” offset wheels on a lt285/70r17 10 ply tire. Tires stick out about 3” from the fenders. Weighs about 1500 loaded down.

Tows 100% fantastic and my cruiser doesn’t know it’s there.

Thank you for the feedback. @Clrussell your setup looks great and thanks for the weight and spec info. This is just about what I am looking to build and up with.

I’m towing a 416 style trailer and find it to be a little too narrow. You really cant see it behind the JKU, not a problem for forward but a challenge and a half to back up. If you have access to both sides, wider would be no big deal. If you have a lid that hinges along one side (common) leaning over to reach the far side becomes annoying. Even in my current rig, leaning across is challenging.

All things considered, I love my trailer, but If I ever build custom, it will probably be a little wider and have a differen’t style of access lid, more like a contractor topper with hatches on both sides.IMG_2517.jpeg

My little home-made military style trailer has the same track width as my 46 Willys. So narrower with the TJ, and even more narrower than my JLU. Tub is 40" x 50". 99% of the time it has been pulled by my TJ when overlanding.

Build thread if interested: https://www.jeepforum.com/threads/mini-harbor-freight-type-trailer-ultimate-build-up-thread.1180456/

I've never had an issue with having different track widths (TJ vs. trailer) on the trail or on the highway. I had the tub built tall so I could stack two 8-gallon Rubbermaid Action Packers on top of each other. The lid hinges on the passenger side, and sometimes yes it is a bit of a pain to reach stuff against the passenger side of the tub. Doable, just a pain sometimes.

FWIW, I’d focus more on length than width (middle school jokes, aside) as the stock m100/416 is very sensitive to loading and balance. Clrussell has an extended tongue and it looks equal in length to NaterXJ6 Chaser trailer (I have a Chaser as well).

I’ve had both; a 1966 M416 and a 2006 Chaser. Pulled behind Tacomas and a 100 series LC so the tracks didn’t match, but I didn’t see that being an issue. I wouldn’t want it any wider for reaching across, as others have said. At least the Chaser generally comes with a tailgate for additional access. I’d also be sensitive to having trailer tires outside the width of the fenders as a stone thrown forward could take out a rear window.

Yes, mine is a 2007 Chaser. I’m probably owner #4 or maybe 5? I took it completely off the frame and did some significant work, including a 3-position telescopic tongue with a fully rotating pintle ring. It deals with the length issues nicely, although it didnt tuen out quite as awesome with respect to fit and finish as I hoped for.
