The 6x12 is the long-deck open trailer at Route 66 Auto Repair in Upland. Renters pick it for long lumber, fence panels, a full garage cleanout or a bathroom demolition. It asks more of your tow vehicle than the smaller sizes, so check your rating before you book on uhaul.com. Our technicians check the hookup for free before you leave our lot in Upland.
What jobs call for a 6x12?
- Long lumber, trim and fence rails for a weekend build
- Drywall and sheet goods laid flat
- A full garage or shed cleanout headed for the transfer station
- Demolition debris from a bathroom or kitchen remodel
- Patio furniture sets and backyard play equipment
What about loads that stick out the back?
Keep long items inside the deck when you can. If a load extends four feet or more past the rear, California requires a red flag on the end in daylight and a red light at night. Tie long material at the front and back so it cannot slide under braking. Pipe and rebar can shoot forward in a hard stop, so block them against the front rail.
Hauling demolition debris
Tile, plaster and concrete are heavy for their size, which is how people overload a big trailer without noticing. Spread the load across the deck with a little more weight just ahead of the axle, and stop well short of the rails with dense debris. Cover dust and small pieces with a tarp. Put broken glass and sharp metal in separate containers so nobody gets cut at the landfill.
Our 6x12 utility pickup process
Step 1: Confirm the pairing
We look at your reservation to see the tow vehicle it lists.
Step 2: Walk the deck
Deck boards, rails, tires and tie-down points are checked and photographed.
Step 3: Hook up
Ball size, coupler latch, pin and crossed chains are set.
Step 4: Test lights
Brake, turn and running lights are verified at the rear.
Step 5: Check the stance
We look at how your vehicle sits with the tongue on the hitch and review the hitch rating.

How pricing and timing work
U-Haul sets the 6x12 utility rate and shows it on the U-Haul dealer page (opens in a new tab). Remodels often run longer than planned, so match your rental dates to the real job schedule. Paid tow vehicle work, such as a brake system inspection, starts with the fee stated at the counter and a written estimate before any repair.
Aftercare
Shovel and sweep the deck clean, pull any stray nails or screws, and photograph it before return. Need to roll equipment on next time? The 6x12 with ramp is the ramp version. A lighter job may fit the 5x8 utility trailer. If the load is boxed household goods, the 6x12 cargo trailer keeps them covered.


Frequently asked questions
How much can a 6x12 utility trailer hold?
Capacity can vary by unit, so confirm current capacity on uhaul.com for your reservation. Then check that your vehicle's towing rating covers the trailer and the load together.
What vehicle do I need for a 6x12 utility trailer?
Usually a pickup or larger SUV with the right hitch and a rating that covers the loaded trailer. The uhaul.com reservation checks the pairing when you enter your vehicle.
Can I haul concrete or dirt in a 6x12?
You can haul heavy material, but weight adds up long before the deck looks full. Load in partial trips and keep the weight centered just ahead of the axle.
Do I need a flag for long lumber?
If the load sticks out four feet or more past the rear, California requires a red flag on the end in daylight and a red light at night. Keeping long items inside the deck is simpler.
