Question:
I just picked up a 9000 cylinder and need this hose and the quick disconnects for front of tow car and rear of motorhome. I know you have said both sides of rm-921004 are both male ends if so do I need two rm-921004-60 to connect? The one for front of tow car rm-921004-50 is male leading me to believe the rm-921004 has one male and one female end. Thanks for your help.

Expert Reply:
The line that you need to connect the RV to the Towed Vehicle is part # RM-921004-88 from the BrakeMaster kit. You only need one of these. It has a male and female end.
I recommend to use the RoadMaster BrakeMaster Second RV Kit part # RM-98200 that comes with the quick disconnect you need for the RV side and the airline.
All the components you need for the vehicle side can be found in part # RM-98100.
