Have you ever seen a forklift driver loading and unloading your dry van? It’s a sight to behold! There are the aces that glide through the palettes with incredible precision. It seems like they take pride in doing their job well, keeping your sidewall looking good. And then there are those forklift drivers who feel the need to rush like they’re on the racetrack. Your side walls are of no concern to you.

Our engineers think about the risks your trailers face at the dock. We realize that the only person who can care about your sidewalls is you. We are committed to innovating to make our trailers productive, light and strong. We usually strive to improve the performance, durability and quality of our trailers.

We put a lot of thought into the sidewall design of our 4000D-X Composite® dry vans. A closer look shows how we made them special. First, our engineers did something you can’t see. An injected polyurethane foam core securely bonds the outer skin to the inner liner panels. This technology increases the strength and durability of the side walls, without increasing the empty weight of the trailer.


Second, we designed a Without a hitch® inner lining. Our galvanized interior liner panels are riveted with fully recessed fixings to the outer skin and side posts, creating a Snag-Free®, high strength composite wall. This proves very resistant to elevator drivers on a collision course.

Third, our composite sidewall also includes 80K flush steel logistic posts. This engineered, track-tested design maximizes sidewall strength and provides greater cargo-tie-down versatility. This uncompromising design also allows the dry van to maintain 101″ of interior width.


We also put a lot of thought into the exterior of the sidewall. Tested for optimum performance, our strong, lightweight, 0.040” thick aluminum exterior side liner uses the strength of the foam bonded to the interior liner panels to distribute stress to the sidewalls. We also coat the exterior sidewall with Ultra Road Shield™ Plus (URS+) ASTM-tested, this two-coat acrylic system with urethane primer improves corrosion protection, minimizes the effects of weathering and keeps the trailer more beautiful, longer.

We designed the 4000D-X Composite® TBR for heavy-duty applications. The high bottom rail is 10″ taller and 50% thicker at ground level than on our standard dry van. The high mounted wear strip provides more strength and durability against a careless forklift driver.


Beyond the side wall, we added a stainless steel rear door frame. This corrosion-resistant frame reduces maintenance costs and increases resale value, and its 110 1/2″ door opening height allows for increased clearance for forklifts. Finally, our integrated sill plate of 27″ deep is fully welded to the buckplate and side gussets. This eliminates floor deterioration below the sill and provides the optimum strength to resist dock plate damage and forklift impacts.

We’ve put a lot of thought into making our sidewalls stronger, more durable and better for the customer. For more information, contact your local utility dealer. You can find them at
