A tilt trailer tips its deck to create a loading path. A GoodMFG® hydraulic drop deck trailer lowers its chassis toward the ground, providing a short, low-angle approach onto the deck instead. That makes loading wheeled equipment and other cargo more manageable, without positioning separate loading ramps. Hydraulic controls let you adjust the trailer’s height during setup. When comparing options, check the model’s loading dimensions, carrying capacity, and operating instructions to match the trailer and loading setup to your equipment.

Standard trailers may be available from stock for immediate pickup. When a standard trailer needs to be built, our general estimate is approximately three weeks for production and delivery. Custom trailer production generally takes approximately 10–12 weeks after we receive your finalized specifications and requests. Transportation and pickup arrangements are confirmed separately. Availability, customization, production schedules, and delivery location can affect these estimates. Contact your dealer or GoodMFG® representative to confirm the current schedule for your order before arranging pickup or transportation.

GoodMFG® modular structures are factory-built units that provide adaptable space for storage, offices, retail, and other business uses. Use a module on its own or combine compatible units to create a larger layout. Standardized components support consistent construction and assembly, with much of the building work completed before the unit reaches your site. This streamlines on-site setup and gives you a practical alternative to constructing the entire space on location. Some basic setups can be assembled in a matter of hours on a prepared site.

GoodMFG® modular structures give your business room to grow without starting over every time your needs change. Factory-built construction reduces the amount of building work needed on site, creating opportunities to shorten installation and manage on-site labor costs.

Compatible units can be linked, stacked, reconfigured, or relocated in suitable configurations, helping your space keep pace with your operation. That adaptability gives you more ways to keep using the structures you already own instead of replacing them when your needs change.

Your overall cost, timeline, and expansion options depend on the selected models, layout, delivery, site preparation, utilities, and approval requirements. Our team can help you explore a setup that fits your operation and budget.

Weight depends on the model and installed options. For reference, our storage models have the following estimated dry weights: GM13ST, 1,900 lb; GM13HQ, 2,200 lb; GM19ST, 2,300 lb; and GM19HQ, 2,600 lb.

These figures apply to the named storage models. Office, LED-equipped, and customized structures have their own specifications, and installed equipment or stored contents can change the weight being transported or lifted.

For delivery and placement planning, check the specifications for your exact model and confirm the configured unit’s weight with your dealer or GoodMFG® representative.

GoodMFG® modular structures can be linked side by side or stacked in compatible configurations, allowing you to create more space without starting from scratch.

The number and arrangement of units depend on the selected models, intended use, loading, and site conditions. Our corner-caster and connector system supports a range of expanded layouts.

Tell us what you want the space to do, and our team can help you plan the arrangement and confirm the applicable stacking limits, connections, foundation, and anchoring requirements before installation.

Standard modular structures may be available from stock for prompt pickup or delivery. When a standard unit needs to be built, our general estimate is approximately three weeks for production and delivery.

Custom modular-structure production generally takes approximately 10–12 weeks after we receive your finalized specifications and requests. Transportation, placement, and any additional site work are scheduled separately.

Timing depends on the model, installed options, production schedule, and destination. Contact your dealer or GoodMFG® representative to confirm availability and an order-specific schedule, including what must be ready at your site before delivery.

Your permitting needs will depend greatly on the specific location where you intend to use the unit. Our experts can help you investigate local permitting requirements to determine whether installation will be feasible in your area.

Pickup timelines for modular structures depend on the customization.

• Standard structures (no customization). There’s a good chance we have a version in stock for immediate delivery. If not, a new basic modular structure can generally be built and delivered within 3 weeks. This applies to common modular office buildings and mobile office builds as well.
• Custom modular structures. We can generally build your custom modular structure within 10 to 12 weeks of receiving your final specifications and requests.

Please note these timelines can vary slightly as our production calendar fills up, so always verify your specific delivery or pickup date with your Good Manufacturing representative or local dealer.

We currently have open dealership territories available in most states within the United States. We are actively looking to expand our network.

We have experience working with various dealership setups, from large established lots to smaller start-up operations, and even dealers in the early stages of a new location. Our successful dealers typically have at least a few Good Trailers on their lots for demo purposes, allowing customers to see the functionality of our hydraulic drop deck lowering trailers.
