There is a reason the M416 trailer keeps showing up in overlanding conversations. It is compact, rugged-looking, and simple enough that owners can adapt it to their own kind of travel. But a surplus military trailer and a modern M416-style overland build are not the same purchase. Before you hunt for one, it helps to know what the original was designed to carry and what it may take to make an aging example road-ready.
What is an M416 trailer?
The M416 is a quarter-ton, two-wheel military cargo trailer associated with the M151 MUTT. Its steel cargo tub, squared-off fenders, and compact footprint made it a useful utility trailer long before rooftop tents and camp kitchens entered the picture. Today, those proportions make it a familiar starting point for DIY overland conversions and newer trailers inspired by the original.
M416 trailer specs at a glance
- Empty weight: approximately 670 lb
- Rated payload: approximately 500 lb
- Gross weight: approximately 1,170 lb at the original rating
- Overall dimensions: approximately 108.5 in long × 60.5 in wide × 42 in tall
- Interior cargo bed: approximately 41 in wide × 72 in long
- Original brakes: no trailer braking system
These are reference figures for the original trailer, not a promise about a particular surviving example. Repairs, modifications, accessories, and replacement components can change its weight and usable capacity. Check the data plate and weigh a prospective purchase before planning your build.
M416 vs. M416A1 vs. M416B1
The M416 and M416A1 are closely related quarter-ton trailers associated with the M151 MUTT. The M416B1 is a distinct variant associated with the Marine Corps' M422 Mighty Mite. It used smaller 6.00×16 tires on M422 wheels and featured details such as airborne lifting rings and side-mounted jerry-can holders. Reported production of the B1 is around 2,000 units. If originality matters to you, inspect the data plate and hardware rather than trusting a listing title alone.
Why overlanders still want one
An M416 can follow a smaller tow vehicle without the bulk of a full-size cargo trailer. Its open tub is a blank canvas for storage, a cover, or a rooftop-tent setup. The appeal is real, but so is the original 500 lb payload limit: water, a fridge, recovery gear, batteries, and a tent can consume it faster than you might expect. Add up your complete loaded kit, including the weight of any modifications, before assuming the original running gear is suitable.
What does an M416 trailer cost in 2026?
There is no dependable nationwide sticker price for a surplus M416. As a rough shopping reference, a complete project trailer may be advertised around $700–$1,500, while a restored example may be listed around $1,500–$3,000; outfitted overland conversions can cost substantially more. Those are illustrative asking-price ranges from enthusiast listings, not a current market appraisal. Local supply, title status, rust, tires, axle condition, and the quality of prior work can swing the actual deal considerably.
The purchase price is only the beginning of a restoration budget. Inspect the tub and frame for corrosion or cracks, confirm the coupler and safety connections are appropriate for your tow vehicle, and allow for bearings, tires, wiring, lights, and any brake or suspension work your intended load calls for. Check your state's registration and trailer-brake requirements before buying an untitled project.
Original M416 or modern M416-style trailer?
Choose an original if you enjoy restoration, want the military character, and can inspect its condition closely. Budget time for repairs and paperwork as well as parts. Choose a modern interpretation if you would rather start with a purpose-built camping platform and compare current specifications instead of inheriting decades of unknown repairs.
For example, the YT416 Overland Edition draws on the M416 silhouette while offering a different, contemporary setup. Compare its published bed size, suspension, brakes, weight rating, and available equipment with your real packed weight and tow vehicle before deciding. The YOLO YT416 is worth a look if you love the shape but want to skip the surplus-trailer restoration project.
Frequently asked questions
How much does an M416 trailer weigh?

What are the M416 trailer's dimensions?
Approximately 108.5 in long, 60.5 in wide, and 42 in tall overall, with an interior bed around 41 × 72 in.
Does an original M416 have brakes?
No trailer braking system is listed for the original. Check local requirements and your tow vehicle's limits before towing a loaded or modified example.
Can you buy a new M416?
Not a new original military M416. You can buy modern trailers inspired by its shape, including the YT416.
Is an M416 big enough for overlanding?
