Light Duty
Trailers, dump inserts, light truck beds
Bolt-on solutions for landscape trailers, contractor dumps, and small material haulers. EZ-Fit kits install fast with no cab electrical.
Class 1 – 3 · Light Commercial
Pickups, utility bodies, light dumps · GVWR 6,000 – 14,000 lbs
Light-commercial pickups and dump inserts. EZ-Fit and semi-automatic options fit most stake-bed and short-bed configurations.
Class 4 – 6 · Medium Duty
Box trucks, mid-size dumps · GVWR 14,001 – 26,000 lbs
Mid-size dump bodies and cab-over chassis. Semi-automatic systems give a good cost-to-cycle-time tradeoff.
Class 7 – 8 · Heavy Duty
Tandem & tri-axle dumps · GVWR 26,001 – 33,000+ lbs
The flagship category. Includes Super 10s, Super Duty, and tag-axle configurations. Automatic systems are the default choice.
Class 7 – 8 · Trailer
Rear-discharge dump trailers
End-discharge dump trailers towed behind a tractor. Common in aggregate, demolition, and bulk material haul. Compatible with all automatic tarp systems.
Class 9 · Severe Duty
Off-highway, super dumps · GVWR 33,001+ lbs
Heavy-duty articulated and super-dump configurations. Open 9000M handles longer beds and severe-service applications.
We’ve fit our systems to almost everything that hauls. Tell us about your truck and we’ll spec a system.
Hauling & Tarping Regulations
Federal rules require secure cargo on all commercial vehicles. Most states add additional requirements specific to dump trucks, aggregate haulers, and waste vehicles. Failure to tarp can mean fines, points, and CSA score impact.

Common questions about fitment, classes, and choosing the right system for your truck.
Truck classes are based on Gross Vehicle Weight Rating (GVWR). Class 7 covers vehicles from 26,001 to 33,000 lbs — typical of single-axle dump trucks and medium tandem dumps. Class 8 covers everything over 33,000 lbs, including most tri-axle dumps, Super 10s, and Super Duty configurations. Both fit our automatic systems.
A standard dump truck has 2 or 3 axles. Class 7 single-axle dumps have 2 axles. Tandem-axle dumps (most Class 8) have 3. Super 10s have up to 5 axles, with the additional axles being lift axles that lower for added load capacity. Super Duty and tag-axle configurations can run 4–6 axles total.
A Super 10 is a Class 8 dump truck with 5 axles total — the standard 3 axles plus 2 additional lift axles that lower under load. The lift axles distribute weight to comply with bridge formula limits, allowing higher legal payloads. Super 10s are popular on the West Coast for aggregate hauling. Our automatic systems are the standard tarp choice for Super 10 configurations.
Yes — federal regulations require secure cargo on all commercial vehicles, and every U.S. state has additional requirements specific to dump trucks and aggregate haulers. Coverage is required when hauling material that could spill, blow off, or shift. Specifics vary by state — see our state-by-state tarping guide.
Yes. Our EZ-Fit kits are specifically designed for landscape trailers, contractor dump inserts, and small-to-medium open-bed configurations. Most install in under an hour and don’t require any cab electrical. See the Landscaping class for compatible options.
Your GVWR is on the door-jamb sticker (driver’s side) and on your vehicle registration. It’s the maximum loaded weight rating set by the manufacturer. Once you have the GVWR, the truck class is set: 0–6,000 (Class 1), 6,001–10,000 (Class 2), 10,001–14,000 (Class 3), 14,001–16,000 (Class 4), 16,001–19,500 (Class 5), 19,501–26,000 (Class 6), 26,001–33,000 (Class 7), 33,001+ (Class 8).
