Any ideas what this lever is for. It’s tied into the air system. This is on a 1996 45ft model. Thanks

Could be used to activate your trailer air brakes separately from your coach brakes. 18 wheelers have a similar lever, helps them to prevent or recover from a skid.

Very loud train horn

It does have the train horn option. I tried moving it but did not notice any difference. When I turn the gate valve on it blows, maybe that will regulate the horn it didn’t seem to throttle it back, but I will try again.
Thanks for the replies

Does it have an air brake connection for the towed vehicle? If so, I think Forest has provided the answer.

It is for trailer brakes on a trailer but could have been changed into a train horn. It is for a trailer you should have a separate valve on the dash to charge the trailer. Hope it helps.

Thanks for the replies. I do have a little air fitting, does this look like it is for a trailer? And what type of trailer has air brakes. All the trailers I think of have electric brakes.

Heavier trailer tend more toward air brakes than lighter trailers. Also, some cars that are being towed are equipped with air brakes.
