Truck Compatibility Guide

TUNE M1 ON A
HONDA RIDGELINE

The Ridgeline is the only unibody truck in the M1 lineup, it rides smoother than anything else here, has solid payload numbers, and a hidden storage trunk nobody else gets. The full picture.

TL;DR
  • Variant: mid-size Tune M1 fits the Ridgeline (5'4" bed, 2017–present)
  • Payload range: ~1,509–1,583 lbs, consistent across trims
  • Unibody: officially supported by Tune, rides smoothly under load
  • In-bed trunk: still accessible with M1 mounted, free lockable storage
  • Check your door sticker. Then use the calculator.

M1 Compatibility

✓ Compatible

The mid-size Tune M1 fits the Honda Ridgeline 2017–present. The Ridgeline has a 5'4" bed (64" long x 60" wide). Tune officially lists it as a supported truck.

The Ridgeline is an outlier in the M1 world: it's the only unibody truck on the compatibility list, and it comes with some genuine advantages that body-on-frame trucks don't have.

📍

Your payload number is on the sticker inside your driver's door jamb. The Ridgeline's advertised specs reflect the lightest configuration, your actual sticker reflects your truck. See the payload guide.

The Unibody Factor

The Ridgeline uses unibody construction, the body and frame are a single integrated structure, like an SUV or car. Every other truck on the M1 compatibility list is body-on-frame (separate ladder frame bolted to the body).

What this means for M1 use:

  • Smoother ride under load. The Ridgeline's fully independent suspension (including rear) handles the M1's weight more comfortably than leaf-spring trucks. Less bouncing on rough roads, better highway manners.
  • Respect the payload limit. Unibody trucks have less tolerance for exceeding their rated payload than body-on-frame trucks. Stay within your door sticker number. No fudging.
  • No aftermarket frame mods. The Ridgeline's structure doesn't support heavy aftermarket bumpers, winches, or frame-mounted accessories the way a body-on-frame truck does. This is fine for M1 use, you probably aren't adding steel bumpers to a Ridgeline.
💡

Note: GFC does not support the Ridgeline. The M1 does. This means the Ridgeline is actually one of the trucks where the M1 has no direct competitor. It's the premium pop-top option for Ridgeline owners.

Honda Ridgeline Payload by Trim

The Ridgeline has the tightest payload spread of any truck on this site, only 74 lbs separates the highest and lowest trim. Every Ridgeline is AWD standard.

Trim (2026) Approx. Payload M1 Build Verdict Notes
Sport ~1,583 lbs ✓ Workable Highest payload. Lightest trim.
RTL ~1,544 lbs ✓ Workable Leather, heated seats add some weight.
TrailSport ~1,521 lbs ✓ Workable Off-road suspension and underbody protection.
Black Edition ~1,509 lbs ✓ Workable Heaviest trim. Still has good margin.
2nd Gen (2017–2025) ~1,480–1,580 lbs ✓ Workable Varies by year and options. Check your sticker.

Every Ridgeline trim is green. The spread is so tight that trim choice barely matters for M1 payload. Pick the one you want and you'll have roughly the same headroom.

The In-Bed Trunk Advantage

The Ridgeline has a feature no other M1-compatible truck offers: a lockable, waterproof trunk built into the bed floor. It's 7.3 cubic feet of hidden storage accessible by lifting the bed floor panel or swinging open the tailgate's dual-action hinge.

With the M1 mounted, the in-bed trunk is still fully accessible. This gives you:

  • Locked storage for recovery gear, tools, or valuables that doesn't eat into your camper interior
  • A place to stash dirty or wet gear separately from your living space
  • Additional organization without adding weight (the trunk is part of the truck)

It's a small thing, but Ridgeline owners consistently cite it as one of the best features of the platform for camper use.

Grand total (with M1)~1,025 lbsWhat you're actually putting on the truck

On a Sport at 1,583 lbs, that's roughly 558 lbs of headroom — very comfortable. Even the Black Edition at 1,509 lbs gives you ~484 lbs of headroom. The Ridgeline is a mid-pack payload truck that works well for the M1 because the numbers are consistent and predictable.

Ridgeline-Specific Tips

  • Expect a noticeably smoother ride than leaf-spring trucks. The fully independent rear suspension makes a real difference when you're loaded up. Highway miles with the M1 feel less punishing on the Ridgeline than on most mid-size alternatives.
  • Use the in-bed trunk. Stash recovery gear, tools, or dirty items in the trunk rather than inside the camper. It's waterproof and lockable — one of the Ridgeline's best features for camper use.
  • No GFC option. GFC doesn't support the Ridgeline, making the M1 the premium pop-top choice for Ridgeline owners. No cross-shopping needed.
  • The payload limit is a hard stop, not a guideline. Unibody trucks have less tolerance for overloading than body-on-frame trucks. If your sticker says 1,509 lbs, that means 1,509 lbs.
  • AWD standard. Every Ridgeline is AWD, which adds some weight vs. hypothetical 2WD but means you don't have to choose between capability and payload.
  • Bed width: At 60" wide (50" between wheel wells), the Ridgeline is wider than most mid-size trucks. Interior space with the M1 benefits from this.

Honda Ridgeline + M1 Questions

Common questions from Ridgeline owners considering the M1.

Can a Honda Ridgeline handle the Tune M1?

Yes. The Ridgeline is officially supported by Tune for the mid-size M1 (2017–present). Payload ranges from ~1,509 to 1,583 lbs depending on trim — solid headroom for a typical M1 build. The independent rear suspension handles the load more smoothly than leaf-spring trucks, which is one of the Ridgeline's real advantages for camper use.

Does the unibody design affect M1 compatibility?

The M1 mounts to the bed rails, which are structurally sound on the Ridgeline. Tune officially lists it as compatible. The unibody rides smoother under load but has less tolerance for exceeding payload limits. Stay within your door sticker number.

Which Ridgeline trim has the most payload?

The Sport at ~1,583 lbs. But the spread is only 74 lbs across all trims, the smallest gap of any truck on this site. Trim choice barely matters for M1 payload.

Does the in-bed trunk work with the M1 mounted?

Yes, the lockable, waterproof trunk under the bed floor is still fully accessible with the M1 installed. It's a genuine advantage: 7.3 cubic feet of hidden storage that doesn't eat into your camper's interior space.
