A decision guide based on what you haul, where you run, and how you work.
“Best” is never one-size-fits-all. A show-truck that logs 70 °F highway miles has different needs than a log hauler crawling mud roads in January. Merritt builds four distinct heavy-duty fender families so you can spec the best heavy-duty truck fender option for your reality. Instead of ranking them 1-to-4, the guide below matches each Merritt fender style to the environment where it outperforms everything else.
| If your priority is… | Choose this Merritt fender | Why it wins in that scenario | Product Image |
|---|---|---|---|
| Classic look with the broadest size/price range | Aluminum & Stainless Rolled | Traditional rolled profile, 36 models / 12 designs; bright aluminum or mirror-finish stainless let you dial in budget vs. bling Merritt Products |  |
| Surviving severe vocational abuse | Aluminum Super-Duty | 1/8″ diamond-plate skin plus internal gussets handle debris fields, pit roads and off-highway impacts Merritt Products |  |
| Maximum spray control & show-truck styling | Deep-Drop & Wrap | Extra-deep skirt follows tire contour; smooth or diamond finish delivers both cleanliness and curb appeal Merritt Products |  |
| Lowest weight & lowest upkeep cost | Poly-Pro HDPE | Flexes instead of denting, shrugs off salt/chemicals, ships as two bolt-together halves for easy handling Merritt Products |  |
How to decide in 3 quick questions
- What’s your abuse level?
- Logging, mining, frac sand → Super-Duty
- Highway, dry van → Rolled or Deep-Drop
- Is weight or appearance more important?
- Every pound matters → Poly-Pro or Aluminum Rolled
- Chrome-level shine → Stainless Rolled or Deep-Drop Smooth
- How much splash control do you need?
- Tankers / haz-mat (keep valves clean) → Deep-Drop & Wrap
- General freight → Half or full Rolled fenders
Real-world pairings
| Fleet type | Common spec | Recommended Merritt fender |
|---|---|---|
| 48-state dry-van | Full tandem, bright finish, weight-sensitive | Aluminum Rolled (.090 smooth) |
| Reefer / food-grade | Full or half stainless for wash-bay durability | Stainless Rolled |
| Heavy-haul / lowboy | Full tandem, diamond-plate grip for step-up | Aluminum Super-Duty |
| Tanker / bulk | Deep-Drop smooth for max splash + easy wash | Deep-Drop Smooth |
| Northern snowbelt | Quarter or full HDPE for salt resistance | Poly-Pro HDPE |
