Probably nothing to do with this problem but this time of the year ya need to check your trailer for wasps nests,they love trailers...Also a simple pedestal like I use in my loading video can make a big difference...

We are the center of the wasp universe on this farm for some reason, so I will be careful with that. (We also seem to harbor all of the mice and rats in the county on our six acres...despite our two mousers in the barn.) Where is your loading video? How can I access that?
