Has anyone had trouble with their cruise control dropping out while towing? I have noticed on my lmm the cruise drops out from time to time. I also get a service trailer warning that lights the brake light and the abs light?

Brake light switch on the brake pedal assembly is probably going out. I replaced mine a couple times, its easy...

Cool deal I will swap it out. I mostly notice it when I start to hit rough roads with lots of bumps generally going up hill. I will try cleaning the grounds and swapping the brake switch.

If you have a Tech 2, you can look at the past 8 "cruise disable/inhibit reasons" in the ECM's history. That would help determine what is disabling cruise...

Bumpy roads is when mine would act up as well when pedal switch was going out.

Alright I have a little more info and have the cruise dropping issue isolated. Its kinda funny. When I am driving with stereo at normal levels cruise never drops out. When I fire up the subs and the rockford amps start drawing juice the cruise drops out every time. I probably need to face the fact I am almost 41 and need to turn it down lol!
