Both the 903 Truck Beds SD Model and FD Model deliver heavy-duty flat deck performance, but their skirted vs non-skirted designs create clear differences in style, utility, and cost.
Design Differences
The SD Model (Skirted) features side skirts that give it a streamlined, enclosed appearance with added storage potential along the sides. The FD Model (Flat Deck Non-Skirted) keeps an open design without side enclosures, maximizing deck space and visibility.
Size Options
Both models offer 84″ and 97″ widths with lengths of 7′, 8’6″, 9’4″, and 11’4″. The SD’s skirts slightly reduce usable side space, while the FD provides full open access across the entire deck.
Pricing Comparison
| Model | Price Range | Example |
|---|---|---|
| SD Model | $3,753–$5,800 | 8’6″ at $3,753 (Tri Star), larger at $5,800 |
| FD Model | $3,099–$4,500 | 7′ at $4,100 (APC), basic at $3,750 |
SD models cost 10–25% more due to skirt fabrication and materials. Installation adds $500–$1,000 for either.
Best Use Cases
Choose SD Model When
- You want a professional, enclosed look for fleets or customer-facing work.
- Side storage or skirt-mounted accessories matter.
- Hauling pallets or equipment where skirts add protection.
Choose FD Model When
- Maximum deck space is priority for large loads.
- Budget is tight (saves $500+ vs SD).
- You prefer full visibility and easier loading/unloading.
Construction and Features
Both use 1/8″ steel diamond plate floors, 4″ C-channel framing, and 39″ tubular headache racks. Rear smooth plate skirts (FD) vs full side skirts (SD) are the main visual/functional difference. Both handle towing, hauling, and jobsite abuse equally well.
Truck Fitment
Compatible with Ford, Ram, GM, single/dual wheel chassis. Measure your cab-to-axle (CTA) distance (typically 40″–60″) before ordering.
Which Should You Buy?
- Contractors/landscapers: SD Model for style + side utility.
- Haulers/towers: FD Model for open space + lower cost.
- Fleets: Mix both based on truck roles.
The SD Model wins for appearance and versatility, but the FD Model offers better value for pure utility. Contact a dealer for exact fitment and current pricing.
