This can be a challenge for those not comfortable with automotive electrical work. Additionally, it is more expensive than basic time-delayed controllers. This system is an excellent choice for those who prioritize smooth, proportional braking and are willing to invest in a professional installation. Skip this if you want a wireless or budget-friendly option.
- Proportional braking senses deceleration and applies trailer brakes in sync
- Large digital display shows voltage, brake output, and error codes
- Three user-selectable profiles for different trailers
Pros: Smooth, proportional braking feels natural and safe; Highly durable construction with a reputation for longevity
Cons: Requires hardwiring; installation can be complex for some users
3. Reese Towpower Brakeman Digital Brake Control: Best Value
The Reese Towpower Brakeman Digital offers a strong balance of features and affordability. In our evaluation, it performs reliably in both time-delayed and proportional modes, though the proportional response is not as smooth as the Tekonsha P3. The digital display is easy to read, and the controls are straightforward. Based on owner feedback, it is a popular choice for budget-conscious RVers who tow medium-sized trailers. The unit is compact and fits well in most vehicles.
However, its proportional mode can feel slightly abrupt during light braking, and the build quality, while adequate, does not match the premium feel of higher-end controllers. This system is best for those who need a reliable brake controller without breaking the bank. Skip this if you tow heavy or large RVs and require the smoothest proportional braking available.
- Dual mode: time-delayed and proportional braking options
- Compact design with bright digital readout
- Compatible with 2, 4, 6, and 8 brake systems
Pros: Affordable price point for a digital controller; Simple interface with easy adjustments

Frequently Asked Questions
Do I need a brake controller for towing an RV?
Yes, if your trailer has electric brakes (most RVs over 1,500 lbs do), a brake controller is required by law in many states and is essential for safe stopping. The controller activates the trailer brakes in sync with your tow vehicle, reducing stopping distance and preventing sway.
What is the difference between proportional and time-delayed brake controllers?
Proportional controllers apply trailer brakes in proportion to the tow vehicle’s deceleration, providing smoother and more natural braking. Time-delayed controllers apply a preset amount of brake force after a delay; they are simpler but can cause jerky stops. Proportional is generally preferred for RV towing.
Can I install a brake controller myself?
It depends on your skill level and the controller type. Wireless models like the Curt Echo are easy to install. Hardwired controllers require connecting to the vehicle’s brake wiring and mounting; many owners opt for professional installation to ensure proper function and safety.
How do I choose the right brake controller for my RV?
Consider your trailer type and weight, towing frequency, and budget. For heavy or frequent towing, a proportional controller like the Tekonsha P3 is ideal. For occasional towing or multiple trailers, a wireless model may be more convenient. Also ensure compatibility with your trailer’s brake type (electric or electric-over-hydraulic).
What is a breakaway system and do I need one?
A breakaway system activates the trailer brakes if the trailer becomes disconnected from the tow vehicle, preventing a runaway. Most states require it for trailers over a certain weight. Many brake controllers include a breakaway feature, but you may need a separate battery and switch if not built-in.
