      Annual Trailer Maintenance Checklist

      Some things you should consider when preparing to store your trailer for the off season - so it's ready for next year's adventures!

      1. Wheel bearings: check for play in the wheel bearings. You can lift each corner of the trailer off the ground with your leveling jack, grab the top and the bottom of the tire and check to make sure that there is zero play. Give the tire a spin and make sure it rotates freely and there are no noises, and that nothing is binding up in the hub or brake system. 
      2. Unplug the safety breakaway switch and ensure the electric brakes energize. 
      3. Check the Hopkins Battery Box by pressing the button on the front to ensure it is charged. This battery would benefit from being charged periodically in the off season.  
      4. Frame: check for damage or dirt hanging up in the c channels. 
      5. Suspension: check for loose fasteners (Timbren Reference Article!) check camber with the trailer on a level surface. Use a bubble level across the top and bottom of the rim face and check with the trailer parked in several locations on a flat concrete floor to obtain an average. 
      6. The batteries supplied by OGT are maintenance free – you cannot service the electrolyte. It is always good to double check that the connections are tight. 
      7. Check the sealant around the roof mounted fan for cracks or other voids. If this sealant requires service, it is recommended the work be carried out at an RV (Recreational Vehicle) repair facility. 
      8. Lubricate all the locks and latches with dry graphite lube, or with Teflon/PTFE spray lube. 
      9. Treating the rubber bulb seals with silicone spray will help extend their life and keep them working well. Ensure whatever product you use is compatible with rubber. 
      10. Check to make sure the 7-pin connector is in good condition and that all the trailer lights are functioning properly – the off season is the best time to spend troubleshooting if something needs repair. 
      11. If you have a roof top tent or awning(s), make sure the tent is free of debris, is dry, and clean before folding up and storing for a longer period of time.   
      12. Inspect and grease the CU offroad coupler system, if equipped. You can pump clean grease in via the zerks - use plenty and be ready to clean up any dirty grease that is expelled during the process.  CU recommends removing the trailer side coupler and allowing any water present to drain - via removal of the visible seal, and to cycle the grease gun more than 12 times. Make sure to rotate the coupler while adding grease in order to ensure even distribution of new grease.
      13. Check the safety chains for damage and make sure that the bolts attaching them to the hitch are tight.
      14. Examine all 3 wheels and tires. Is there physical damage to the tread or sidewall? Weather cracking? How are they worn? Are the wheels intact, any rub marks, dents?
