The Ford F-350 Super Duty is sold in Regular Cab, SuperCab, and Crew Cab configurations, paired with 6.75-foot or 8-foot beds, and available in both single rear wheel (SRW) and dual rear wheel (DRW) axle configurations. DRW trucks are a distinct body envelope — the dual rear axle widens the rear fenders by approximately 6 inches compared to SRW. An SRW-patterned cover applied to a DRW F-350 will not seat correctly at the rear fenders. DaShield maps F-350 covers by year, cab style, bed length, and SRW/DRW at purchase.

The OBS generation (1992–1997) is a separate body from the 1999-and-later Super Duty. These trucks share only the F-350 name with current Super Duty models — cab proportions, front clip, and rear fender geometry are distinct. OBS covers are patterned to OBS model years. A current Super Duty pattern will not fit an OBS cab correctly.

The primary outdoor threat for F-350 owners in the Great Plains, Midwest, and Mountain West is hail. PDR on a Super Duty following a moderate hail event runs $3,000–$10,000+. Aluminum Super Duty hoods cannot be hammer-and-fill repaired — when hail damage exceeds PDR limits, the hood is replaced at $2,000–$5,000. A DaShield Ultimum truck cover at $229 with a Lifetime warranty addresses that risk across the full body surface. Designed in Buena Park, California.

For the Ford F-350 specifically, three factors determine whether a cover actually fits and protects the truck.

Factor 1: SRW vs. DRW rear body pattern. The DRW F-350 carries a rear body envelope approximately 6 inches wider than the SRW at the outer rear fenders. A cover not patterned to DRW will pull tight across those fenders on a dually, creating pressure at the fender crown and leaving the outer edges exposed. DaShield builds separate rear hem geometry for DRW trucks — the forward sections from cab to mid-bed are shared with the SRW pattern; the rear section is DRW-specific. Selecting SRW or DRW at purchase is required before a pattern is assigned.

Factor 2: Generation-specific body match. The OBS F-350 (1992–1997) has a different cab roofline, front clip, and rear fender profile than the 1999-and-later Super Duty. These are not variant differences within the same platform — they are separate body architectures. DaShield patterns OBS covers to OBS model years. Current Super Duty patterns do not transfer to OBS trucks regardless of cab configuration.

Factor 3: Hail energy absorption across the full body surface. The Ultimum's multi-layer woven construction distributes hail kinetic energy laterally across the cover surface before it reaches the panel below. The mechanism is energy distribution: the woven laminate catches the hailstone and spreads the force across a larger area, reducing the localized pressure that causes permanent panel deformation. On an F-350 DRW with wide rear fenders, a full-body DRW-patterned cover is the only configuration that protects the outer rear fender surfaces — these panels are otherwise fully exposed during a hail event.

The Ultimum is $229 truck price, Lifetime warranty. Woven outdoor covers are wiped clean with a damp cloth — machine washing degrades the laminate and is not supported. The UHD at $209, 5-layer woven, 5-Year warranty covers carport and partial-shelter F-350 owners who have overhead protection but need wind-driven and UV management from open angles.
