Lights work fine when i pull my horse trailer with my 2015 Chevy 2500. Bought $15 Curt 7 pin plug tester and it works fine with my 2015 Chevy 2500. Horse trailer lights and the 7 pin tester do not work with my new 2023 Chevy 2500. Dealer is telling me "some trailers with LED lights do not draw enough current for trailer lighting to operate properly" and suggests I add "load resistors" to all my trailers that have LED lights. See page 2/6 of the attachment below. He said my 2023 Chevy 2500 trailer plug passes all the tests on their $8k machine and there is no problem with my new truck and the problem must be with my horse trailer lights and the Curt 7 pin tester. I disagree since the horse trailer lights and Curt 7 pin tester works with my 2015 Chevy 2500. Most all newer trailers have led lights and the lights should work with a brand new truck designed to pull trailers. Anyone experiencing the same thing?
