The MultiPro MidGate expands the Sierra EV load floor to 10 feet 10 inches, when properly equipped. This folding cabin partition allows drivers to securely transport extra-long items without leaving the tailgate open. Discover how this architecture changes daily hauling for professionals and weekend adventurers alike.
Driving a truck means managing long, awkward cargo. Traditional pickups force you to leave the tailgate down or angle items precariously over the roof when hauling materials. General Motors engineers solved this physical challenge by eliminating the solid steel wall separating the cab and the truck bed on this electric platform.

Translating MidGate Utility
The MidGate operates by folding the rear seats flat and dropping the back cab wall directly forward into the cabin. When you fold this partition down, the standard 5-foot 11-inch bed instantly lengthens. By deploying the load stop on the standard MultiPro Tailgate, you achieve a maximum of 10 feet 10 inches of protected cargo length, when properly equipped.
For everyday work crews hauling lumber, this translates to keeping 10-foot boards completely flat inside the bed. Because the materials are pushed deep into the cabin partition, you never have to worry about cargo sliding out into traffic during acceleration. You can verify the specific weight capacities and dimensional limits of the truck bed on the official GMC electric truck specification portal.
Flexible Cargo Configurations
The beauty of the MidGate is its modular design. The wall splits in a 60/40 layout, mirroring the rear seat structure. The following table explains how these specific configurations benefit daily hauling.
| MidGate Configuration | How It Operates | Everyday Buyer Benefit |
|---|---|---|
| Standard Bed | MidGate closed and locked upright. | Provides traditional 5-foot 11-inch exterior cargo space while comfortably seating three adults in the rear. |
| 40 Percent Split | Folds down the passenger side of the rear wall. | Allows you to haul a 10-foot kayak inside the vehicle while keeping two rear seats available. |
| 60 Percent Split | Folds down the driver side of the rear wall. | Provides wider interior pass-through space for sheet goods while retaining one rear passenger seat. |
| Full Open Cab | Folds the entire rear wall and removes the rear glass. | Creates maximum interior cargo length for massive lumber loads or a completely enclosed, weatherproof sleeping space. |
| (Note: Maximum cargo capacities and hauling metrics are achieved when properly equipped). | ||
