For anyone already flat towing the JGC, I’m putting my planned flat tow configuration to gather any real world experience comments. My current configuration is a 2020 Newmar King Aire 45’ towing a 2019 RAM Longhorn 1500.
1. Tow bar: Roadmaster Nighthawk- Currently use, suitable for JGC 4xe weight (supports up to 8,000#)
2. Tow interface: Roadmaster baseplate kit 521461-5. Similar to current config which I like
3. Electrical Connection: 6-Way - supports battery connection between RV & JGC. Breaker
Prevents battery drain from possibly active JGC systems (air suspension pump, PS pump, brake pump, etc)
4. Brakes: Demco Air Force One “AFO” - Have been successfully using this for over 4 TOADS and 3 RVs.
Proportional bake using RV air brake line. Uses small air cyclinder on bake pedal and supplies vacuum for
brake main cylinder. May need slight configuration change if JGC has different brake system.
5. Break-away: Demco AFO
6. Diode-Or’d connection to tail lights.

What to confirm:
A. Does JGC use an electrical pump/etc for brakes? Active when being towed? Supplies vacuum?
(if it is actually a vacuum system then possibly “T” tap between AFO & vacuum line with back flow preventer)
B. Ensure auto park brake feature can be disabled (a can do this on my 2019 RAM) to prevent park brakes from
engaging while towing.
C. Determine what systems (steering, brakes, suspension, etc) are active during towing and ensure that they
are adequately addressed.
