CruisemasterClass - Ep. 13. Coupling Maintenance 

Really good and informative video -- thanks!

Do you grease the pin or can you use a silicone spray as this keeps the unit clean.

My hitch jams on the pin and will not release .I can drive forward and back , but it still does not release . It is well maintained and lubricated . How do I get it to release ? Leaving the van attached to the vehicle is not always acceptable at some caravan sites .

When you checked the tow pln, the "O" ring is missing, but there was no comment about this.

Hi, I have a problem with my DO35 where it is creaking at the forward and back joint. Any suggestions on how I should deal with that as it doesn’t have a grease nipple on that joint? Chris
