Thanks @gemarsh I got the relay&LED installed and tested today along with a wireless remote and solar charger through the 7-way plug.

thank you, looks like I have a weekend project to install

Kind of an old post, but on one of my trailers the emergency breakaway system has LED lights showing the battery status, and when the truck is on, it does show the status as charging the breakaway system battery. I guess you could put a meter on the trailer battery with the truck off, and see if the reading increases when you start the truck. I don't know if it is a regulated 12v to the back, or a higher (alternator) voltage for charging.

Seems the towing forum is not getting a lot of views, so I'll try this here. I have a 2020 Sierra 1500, and just purchased a dump trailer for occasional personal use. There are general reports (not vehicle specific) of people blowing the charging circuit fuse if they don't unplug dump trailers prior to using the hydraulics. It seems to stem from a low charge on the trailer battery, and then drawing too much current through the tow vehicle charging system when operating the lift. With everything computer controlled in these new vehicles, is there a built in protection from this type of occurrence, where I don't need to be mindful to unplug the trailer prior to operating the dump hydraulics?

Agreed, and GM must be done now, the update finally came in this evening.

thanks, still no update on my end.

I have a 2020 built 2/2020, and have version 1.48. Is it safe to say that you had less than v150 and still got the over the air update?

Yup, and have the ding in the paint to prove it. Very worthwhile option for my usage. Makes getting in/out of the bed a lot easier in my case.

my 2020 is running build W119E dated Sep 12 2019

It has been more than 2 months since the announcement. https://www.gm-trucks.com/gm-releases-significant-over-the-air-update-for-2020-silverado-sierra-other-vehicles/ My truck maintains a WIFI connection and also had free onstar connection over the holidays. I have not received the latest OTA update, and I have manually checked for it as well. How many others have gotten it, and how many have not?

I'll be trying this ~$55 option once available https://9to5google.com/2020/09/07/android-auto-wireless-dongle-project/

Was in Normal mode... It's cold for Alabama was lower 60s at the time. I only went a couple miles. I'll see if it continues on a normal trip, thanks all, I learned some things today.

wow, neat, thanks

Truck is steering unusually tight today, tire pressure is good. Figured I'd check the power steering fluid level under the hood. I can't find the reservoir/dip stick location. The manual talks about it, but does not show a location in the engine compartment for that motor. Is it there someplace, if so where, or is this not a user serviceable fluid on a 2020 5.3l Sierra ?
