Buying Guide
- System type: Choose between portable (CURT RVibrake 4), installed (RVibrake Shadow 2), mechanical (RB4001), all-electric (Patriot BRK2022), or vacuum-assisted (Invisibrake) based on your vehicle and preference for portability vs. permanence.
- Installation complexity: Permanent installations require more time and wiring know-how; portable systems offer flexibility for multiple towed vehicles.
- Braking response: Look for systems with quick reaction times (around 0.5 seconds) for safer stops, especially on highways and grades.
- Battery and power management: Systems with built-in battery charging or monitoring help prevent battery drain on the towed vehicle during trips.
- Compatibility: Confirm hitch receiver size (2-inch is common for many systems), vehicle compatibility, and whether the system supports your trailer’s weight class.
- Control interface: Wireless or onboard controllers affect ease of operation. RF controllers enable in-cabin monitoring and adjustments without leaving the RV.
- Safety features: Auto-positioning, tow-mode detection, and automatic braking protection contribute to safer towed setups and reduce manual intervention.
