How to Replace Atwood Levelegs Control System with GAMA Electronics RF340-4PR Controller

Bottom Line Up Front

Your solution to replace the failed Atwood Levelegs system with the GAMA Electronics RF340-4PR-ASL controller is brilliant and exactly what many RV owners need to hear about. For around $235 shipped (versus $3,000+ for a complete Bigfoot system or $400+ for uncertain repairs), you solved your dead control pad problem on your Tiffin Allegro Bay with a more reliable and serviceable system. The GAMA controller provides the same functionality as your original Atwood system but with better build quality and the ability to easily troubleshoot issues yourself. Your custom 3D-printed switch panel that mounts in the original Atwood location is the perfect finishing touch, maintaining the factory appearance while giving you individual jack control that's actually superior to the original design.

Root Causes

Atwood Levelegs systems are notorious for controller failures, especially after rough road conditions like the sketchy roads you encountered during your 800-mile journey from Florida. The control pads use cheap membrane switches and circuit boards that don't handle vibration and moisture well. Even when everything has proper power and all lockout sensors function correctly, the internal circuits can fail intermittently or completely, leaving you with a dead system that's expensive to diagnose professionally.

Your experience is extremely common with Atwood systems - they work fine initially but fail after some road time. The proprietary nature of these systems makes them difficult and expensive to repair, with no guarantee they won't fail again. The $400+ repair costs you quoted are typical, and many shops won't even attempt repairs because replacement parts are often unavailable or cost-prohibitive.

The GAMA RF340-4PR-ASL you chose addresses these root causes by using standard automotive-grade components and simple, repairable circuits. Unlike the Atwood's integrated control pad that fails as one expensive unit, your new system separates the control logic from the user interface, making future repairs much more manageable.

Before You Start

Before attempting this conversion, you'll need solid 12V electrical experience like you mentioned having from your work on trucks, cars, and ATVs. This isn't a beginner-level repair - you're essentially rewiring your entire leveling system. Make sure you have a good multimeter, proper crimping tools, heat shrink tubing, and wire management supplies. Document your existing Atwood wiring with photos before disconnecting anything, as you'll need to identify which wires go to each jack motor.

The GAMA RF340-4PR-ASL requires 12V power and ground connections, plus four control circuits to your existing jack motors. Verify that your Atwood jacks use standard 12V motors (they should) and that you have adequate wire gauge for the current draw. Your existing jack wiring should work fine since you're only replacing the control system, not the actual jacks.

If you plan to 3D print custom components like you did, make sure your printer can handle PETG reliably. Your choice of PETG over PLA was smart for UV stability and durability in the RV environment. Having access to a Cricut machine for stencils is helpful but not required - you could use vinyl lettering or even permanent markers for labeling.

The Repair Process

Start by disconnecting the battery and ensuring it remains disconnected when working with high-current leveling jack circuits, then completely remove the failed Atwood control pad and controller from your dash and compartment locations. Keep the mounting brackets as you did - they'll work perfectly with a custom adapter plate. Document which wires connected to what terminals on the old Atwood controller before disconnecting them. You'll need to identify the power, ground, and four individual jack control wires to properly connect the GAMA system.

Mount the GAMA RF340-4PR-ASL controller in the same compartment where your Atwood controller was located. The unit needs ventilation per manufacturer specifications and protection from moisture. Connect the main power and ground leads using appropriately sized wire - check the GAMA specifications for current requirements. Your existing RV wiring should handle this if wire gauge is adequate for current draw - verify wire gauge requirements and compare Atwood vs GAMA current specifications before proceeding.

The beauty of your custom switch panel approach is that it gives you much better control than the original Atwood system. Wire your four DPST switches directly to the GAMA controller's switch inputs to enable/disable each individual jack, and use the momentary DPDT switch for extend/retract control (the GAMA controller's built-in relay outputs handle the motor loads directly, eliminating the need for external relays). This allows you to run jacks individually or in pairs, which is actually superior to most factory systems that force you to operate specific combinations. However, consult your RV manufacturer's specifications for any required jack sequencing or load balancing procedures to ensure structural safety.

Test each jack individually before final assembly to ensure proper operation and that your wiring is correct. The GAMA system should provide smooth, reliable operation of your existing Atwood jacks. Once everything tests properly, install your custom switch panel in the original dash location using your 3D-printed adapter plate. The factory appearance with improved functionality is exactly what most RV owners want.

Professional Help Needed

While your electrical background made this project manageable, most RV owners should consider professional help for the initial wiring connections, especially identifying which wires control which jacks. An RV technician can quickly trace your existing Atwood wiring and ensure proper connections to the GAMA controller. This typically costs $100-200 in labor but prevents potentially expensive mistakes.

If you're not comfortable with 12V wiring or don't have the proper tools, have a professional handle the electrical connections while you focus on the mechanical mounting and switch panel fabrication. Many RV service centers would be happy to install a customer-supplied GAMA system, especially since it's much more reliable than repairing the original Atwood components.

For RV owners without 3D printing capabilities, consider having your custom switch panel and adapter plate printed by a local makerspace or online service. Your design files could easily be shared with others facing the same Atwood controller failures. Alternatively, the GAMA handheld pendant works perfectly well if you don't want to create a custom dash-mounted solution.
