PJ Trailers | ALGS Aluminum Skirted Body | 4 Integrated Toolboxes & 30K Gooseneck


The PJ Trailers ALGS Aluminum Skirted Body combines the sleek, corrosion-resistant benefits of a lightweight aluminum deck with the maximum utility of an integrated skirted design. Offering top-notch features and hardware—including four integrated toolboxes, side running boards with rear recessed footholes, and an adjustable aluminum tube headache rack—this flatbed is an expertly designed, professional-grade workhorse. Built on a hybrid steel subframe with premium towing components, the ALGS is ready for extreme commercial use across the Magic Valley.

Available Flatbed Lengths & Fitment

The ALGS is manufactured in multiple lengths to match a variety of truck rear-wheel configurations and Cab-to-Axle (CA) measurements. Our common footprints include:

Available Lengths

Short Bed: 7' 0"
Standard/Long Beds: 8' 4", 8' 6"
Cab & Chassis: 9' 4"
Extended Cab & Chassis: 11' 4"

*Exact fitment depends on your specific vehicle's frame width, Cab-to-Axle (CA) measurement, and single (SRW) vs. dual (DRW) rear wheel configuration. Contact Riverside Trailers to confirm the correct dimensions for your chassis.

The Structural Backbone: Hybrid Steel & Aluminum Framing

The ALGS utilizes a hybrid architecture for maximum longevity and weight savings. The primary foundation relies on 4” structural channel steel frame rails, providing extreme towing strength and durability while preventing interior tube rusting. The deck is supported by industry-leading 3" aluminum channel crossmembers. The top working surface is a high-strength Extruded Aluminum Floor Deck, which is stronger than standard tread plate and perfectly withstands rigorous elements.

Comprehensive Standard Features

  • Integrated Storage: Maximize your utility with four (4) integrated toolboxes featuring recessed doors, Black T-Handle compression locks with weather-proof keyholes, and heavy-duty stainless steel strap hinges to resist loosening and corrosion over time.
  • Elite Towing Setup: Pull heavy trailers effortlessly using the 30,000 lb. independently rated Gooseneck Hitch, complete with an integrated 7-way electrical plug. Safely tow bumper-pull loads via the 18,500 lb. independently rated Steel Drop Hitch with full receiver access and integrated safety chain loops.
  • Accessibility & Styling: Features side running boards paired with rear recessed footholes for easy bed access. The exterior boasts sleek Aluminum Radius Fenders and a polished, angled cast aluminum fuel fill.
  • Aluminum Tube Headache Rack: Designed with strong materials to keep you safe when the unexpected happens, featuring integrated LED lighting to make your stop, turn, and tag lights easily visible.
  • Premium Lighting & Wiring: Equipped with 3/4" bullet side markers, a full array of rear skirt lighting (stop, turn, tail, back-up, and tag lights) mounted in a protective aluminum light box with built-in drain holes. Includes a 7-way round and 4-way flat trailer plug on the rear tailboard.

Available Factory Options

Personalize your PJ ALGS to meet your exact job site requirements:

  • Decking Upgrades: Replace the standard extruded aluminum with Apitong Hardwood, Blackwood (rubber-infused lumber), Rumber (composite), or #2 Yellow Pine Treated Floor.
  • Towing & Hitch Options: Upgrade to a massive 24K Rear Hitch (with 2.5" Receiver), install a B&W Turnover Ball (30K Rating), or completely delete the gooseneck box for a solid deck front-to-rear.
  • Headache Rack Configurations: Upgrade to a Super Duty rack for taller cab profiles (60" & 84x84" CA only), or delete the headache rack entirely.
