Hauling Lumber and Drywall on a Flatbed Trailer

Published 2026-09-15 · Ride On Rentals, Delta BC

If you're hauling lumber or drywall in the Lower Mainland, a flatbed trailer from Ride On Rentals in Delta gets the job done. You back up, load, strap, and go. The main things to think about are stacking order, how much overhang you can live with, and keeping sheet goods dry when the rain starts. Here's how to do it right.

What's the best way to stack lumber on a flatbed?

Stack the heaviest, longest pieces on the bottom. That means beams and posts first, then dimensional lumber like 2x4s and 2x6s on top. Keep the load level so straps sit flat. If you're mixing lengths, put the longer pieces underneath and let the shorter ones fill in the gaps. A level load is easier to secure and less likely to shift on the drive from Delta over the tunnel or across the Port Mann.

For drywall, always lay sheets flat, never on edge. Stack them on a clean, dry surface. If you're stacking drywall on top of lumber, put a layer of plywood or cardboard between them to keep the paper from tearing. Keep the stack tight and even. If you have a few odd pieces, tie them down separately so they don't slide around.

How much overhang is okay on a trailer?

Overhang is the part of the load that sticks out past the back of the trailer. A little overhang is fine, but you need to flag it. A red flag or bright cloth on the end of the last board warns drivers behind you. On a standard flatbed, a couple of feet of overhang is manageable. More than that gets tricky, especially in tight city parking or on the Alex Fraser with wind.

Keep the center of gravity low. Don't stack everything so high that the trailer feels tippy. If you're hauling 16-foot lumber on a 12-foot trailer, you'll have four feet of overhang. That's doable but you have to drive slower and take corners wider. Check your straps before you leave Delta and again after the first few kilometers.

What's the best way to protect drywall from rain?

Drywall and rain don't mix. The paper peels, the core turns to mush, and you're left with a useless sheet. In the Lower Mainland, rain can hit any time, even in July. So you need a tarp. Get a heavy-duty tarp that covers the whole load and hangs down over the sides. Use bungee cords or rope to hold it tight. Don't let the tarp flap, it'll tear and let water in.

If you're hauling drywall, put it on the bottom of the stack and cover it with lumber or plywood. That keeps the tarp off the paper and gives you a little extra protection. Also, check the weather before you load. If it's already raining, you might want to wait. But if you have to go, tarp it properly and drive steady. Water pools in low spots, so make sure the tarp is sloped so water runs off.

What should I know about securing the load?

Straps are your best friend. Use ratchet straps that can handle the weight you're hauling. Put them over the top of the load and hook them to the trailer's tie-down points. Space them out evenly, not all in one spot. For lumber, two straps are usually enough for a short load, but three is better for longer stacks. Check the straps after you drive a few blocks, they can loosen as the load settles.

For drywall, use edge protectors where the strap touches the corners. The paper tears easily and a sharp edge can cut through a strap. You can buy cheap cardboard edge protectors or use a folded piece of carpet. Also, make sure the trailer hitch is secure and the wiring is hooked up. At Ride On Rentals, we'll confirm your tow vehicle and hitch setup when you book, so you know everything is compatible before you leave Delta.

What about towing a flatbed in the Lower Mainland?

Most standard trucks and SUVs with a Class 3 hitch can tow our flatbeds. But you need to know your vehicle's towing capacity and the trailer's weight. We'll help you figure that out when you call. Also, check your hitch ball size and make sure the coupler fits. Wiring matters too, most trailers use a 4-pin or 7-pin connector. We'll confirm what your vehicle has and what the trailer needs.

Driving with a loaded trailer in the Lower Mainland means dealing with bridges, the tunnel, and traffic. Take it easy on hills and leave extra room for stopping. The Coquihalla is a different beast, but for local hauls, just be steady. If you're heading out to Langley or the Tri-Cities, watch for steep driveways and tight corners. A flatbed is forgiving, but you still need to think ahead.

Quick questions

Can I haul drywall on an open flatbed in the rain?

You can, but you have to tarp it well. Drywall will soak up water fast, so use a heavy tarp and make sure it's tied down tight. Stack the drywall on the bottom and cover it with lumber to keep the tarp off the paper. If it's pouring, consider waiting for a dry day.

How do I know if my truck can tow a flatbed trailer?

Check your owner's manual for the towing capacity. Most full-size trucks and SUVs with a Class 3 hitch can handle our flatbeds. When you book with Ride On Rentals, tell us your tow vehicle and we'll confirm compatibility, including hitch and wiring needs.

Do I need a special license to tow a flatbed trailer?

For personal use with a standard truck and a Class 3 hitch, you usually don't need a special license. But rules can vary, so check with ICBC if you're unsure. We'll help you pick the right trailer for your vehicle and your load.

What's the best way to secure lumber on a flatbed?

Use ratchet straps over the top, hooked to the trailer's tie-down points. Space them out evenly and use edge protectors where the strap touches sharp corners. Check the straps after a few minutes of driving and re-tighten if needed.
