  • Curt Triflex Brake Controller Intermittent Error Code Trailer Not Connected
  • You are correct in your thinking that the problem is not the trailer since the brakes work properly when hooked up to the neighbor's truck. The issue is most likely the ground on the trailer connector on the Yukon or the Curt Triflex itself part # C24VV. It sounds like you have checked your connections and grounds but it is a good idea to make sure the trailer connector on the Yukon is grounded to clean bare metal surface and that the brake controller itself is grounded properly. The brake...

  • Do Towing Mirrors # CTM2300B Extend Enough to See Behind an 8 Foot Trailer Towed by 2010 Ford F-150
  • I can tell you that with the Original Custom Towing Mirror Slide-On Mirror (Pair), # CTM2300B, installed on your 2010 Ford F-150, the mere fact that they stick out beyond the factory mirrors will allow you to see further behind the trailer than with stock mirrors.

  • Weight Distribution Carrying Case Recommendation
  • The Curt TruTrack Weight Distribution System # C17500 that you referenced should have no problem fitting in the Classic Accessories Tow Bar and Weight Distribution Tote # CA80113 that you also referenced. The WD system that is used in the product pics for the tote is a Reese system that is very similar in size as the Curt. In fact the frame brackets may actually be smaller. You would not need to remove the hitch ball.

  • Will the Ball Mount Adapter # BA-1 Work with the Curt Weight Distribution Shank # C17125
  • Yes, the Ball Mount Adapter, # BA-1, will work with the Curt Weight Distribution Shank, # C17125.
