Weight Distribution and Sway Control -Obsolete for a Self Propelled Trailers?

[turbopilot]

The 2026 Ford F-150 is now in production. Very few changes but some major upgrades to the firmware to detect and prevent trailer sway and ProPower Onboard inverter generator. Ultimately this technology should be much more effective than using fraction devices at the hitch.

From Google Gemini:

The 2026 Ford F-150 continues to refine its towing suite, moving away from simple reactive braking toward a more integrated, proactive stability system. While Trailer Sway Control has been a staple for years, the 2026 updates focus on "smart trailering" technology that works in tandem with the truck’s chassis and software.

Key Changes to Trailer Sway Control​

The 2026 model introduces several software and sensor-level improvements aimed at making the system more intuitive:

• Integrated Stability Control: The system now tighter integrates with AdvanceTrac® with Roll Stability Control (RSC®). This allows the truck to more accurately distinguish between normal road vibrations and actual trailer yaw (side-to-side movement).
• Predictive Software Algorithms: Updates to the software allow the truck to detect the onset of sway faster than previous models. Instead of waiting for a significant oscillation, it can apply minor, selective braking to individual wheels earlier to "nip it in the bud."
• Enhanced Tow/Haul Mode Integration: When in Tow/Haul Mode, the transmission tuning and engine braking now work more harmoniously with the sway control. For example, the 10-speed automatic is recalibrated to stay in the power band longer, providing the torque needed to pull through a sway-inducing gust of wind.
• Camera-Based Monitoring: While the primary sway control uses yaw sensors, the 2026’s available 360-degree camera system features improved trailer coverage modes. This gives the driver better visual feedback on how the trailer is tracking relative to the truck’s path.

Supporting Towing Tech​

The improved sway control is part of a broader "enhanced towing assist" package for 2026 that includes:

Feature	2026 Improvement
Pro Trailer Backup Assist	Updated software for smoother, more precise steering via the control knob.
Pro Trailer Hitch Assist	Faster processing to align the hitch ball with the coupler automatically.
Smart Trailer Tow Connector	Expanded diagnostics that alert you to trailer light failures or battery issues via the 12-inch screen.
Onboard Scales	Now available on more trims to help ensure your tongue weight is balanced (a major factor in preventing sway).

Important Requirement​

To maximize these stability features, especially when towing near the 13,500-lb limit, the Tow/Haul Package (53T)and a weight-distributing hitch are still required. These mechanical upgrades provide the physical foundation that allows the electronic sway control to work most effectively.

And for those who will be using the F-150 Propower Onboard 7.2 kW inverter generator to charge the LightShip there will be some software enhancements for that system.

For 2026, Ford is focusing on software-driven refinements to Pro Power Onboard rather than a hardware overhaul. While the peak outputs remain the same—2.0kW (Gas), 2.4kW (Standard Hybrid), and 7.2kW (Optional Hybrid)—the system is becoming more integrated into your mobile workflow and campsite management.

2026 Pro Power Onboard Refinements​

• Expanded App Functionality: The FordPass app has been updated to include a "View-Only" mode. This allows you to monitor your truck’s power consumption, on/off status, and any overload warnings directly from your phone while you’re inside your RV or at a distance from the truck.
• Utility Idle Mode: This feature has been further streamlined for 2026. It allows the truck to remain "on" to provide power even when you remove the key and lock the doors. This is particularly useful for maintaining power to your RV's fridge or lights overnight without leaving the vehicle vulnerable.
• System Diagnostics & Resets: For the 7.2kW system, Ford has improved the physical interface in the bed. You can now reset tripped breakers directly from the cargo bed outlet panel, reducing the need to jump into the cab to use the SYNC touchscreen for basic troubleshooting.
• SYNC 5 Integration: The 2026 model transitions to a faster infotainment processor. This results in much lower latency when pulling up the power monitoring screens, giving you near real-time data on which "zone" (cab vs. bed) is drawing the most load.
