Do you have a sub panel from your main panel that has been bonded where it should not have been? These things will create an electrical hazard.

Get a multimeter to test the circuit starting at the end of the cord where the trailer is plugged in and remove each part (cords, adapters, other) untill you find the problem.

If you are comming from a standard 120 volt outlet then get a plug tester and test the plug.
X2 on above post.

Usually an open neutral or reversed neutral and ground will create this issue. I run into this in the cable world getting zapped at a ground block for our cable line. Often it is an open neutral and the ground is now being used as its neutral.

Could also be hot and neutral swapped in the receptacle at the house with an open ground.

Measure your 110V extension cord carefully, believe you have the white and black swapped on one end or the other. You you measure voltage with ground and narrow prong measured. Nothing with white and wide prong tested. I've had it happen to me, sloppy repair of cord swapped hot and neutral. Getting it at the hubcaps to grass! If cord is nonpolar like 30 years ago, get rid of it. I can be dangerous bite with the right (wet) connection. You have reverse polarity to every metal fixture aboard.
