M1 Compatibility
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.
Realistic Payload Budget: Ridgeline + M1
| Item | Weight | Notes |
|---|---|---|
| 100Ah LiFePO4 battery | ~26 lbs | Varies by brand |
| Mattress (4" foam) | ~18 lbs | Custom cut to platform size |
| 7 gal fresh water | 58 lbs | 8.34 lbs/gal |
| Camper gear & accessories | ~50 lbs | Estimate, varies widely |
| Driver | ~175 lbs | Use actual weight |
| Passenger | ~150 lbs | If applicable |
| Cab gear (bags, food, etc.) | ~25 lbs | Easy to underestimate |
| Full fuel tank (~19.5 gal) | 123 lbs | 6.3 lbs/gal |
| Subtotal (everything except the M1) | ~625 lbs | What loads onto the truck before the camper |
| Tune M1 (base, mid-size) | ~400 lbs | Dry weight, no gear |
| Grand total (with M1) | ~1,025 lbs | What 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.
