Chassis Ground on a Bigfoot truck camper????

I would subscribe to Delta bravo’s YouTube channel.
It may answer some of your questions.

A.m. solar. com has some good DIY instructions..

That green wire to the propane is about as good as it gets. The purpose is to have the chassis grounded even during a fault or during service when the other grounds might get disconnected. This prevents you from becoming the ground connection. As you know there is no real metal frame for you to create a ground except maybe to the appliances.

Same system I installed.

I was also wondering about the chassis ground. I am getting all my components together now for my bigfoot TC. (2) BB Li batteries, Victron BMV 712, Victron Multiplus 12 2000 80/50 converter/charger. For charging from the truck, Victron Orion TR Smart 12/12/30 DC to DC charger. Solar charging to be added later this summer. I do have a question as to where to attach the case ground(s) - for the new inverter charger for example.

Just subscribed to Delta Bravo :)

Sounds like you have a nice setup going there Gulfman

Thanks for all the reply’s!!!!
All I am trying to do is a have a real basic solar charging system.
I have installed 2 Battle Born 100 amp hour batteries
Added 300 watts of Zamp Solar
VICTON charge controller and shunt
Replaced my original factor converter with a Progressive dynamics lithium replacement
and that’s it . I have a Honda 2000 generator for everything else..
I would have liked to had a more robust system but this was Challenging enough for this 69 year old mind. I would like to give a big thank you to Delta bravo for his help through YouTube comments and his rv.net comments. If you all would like to watch some very Intuitive videos go to Delta bravo YouTube channel. This man’s knowledge on RVs inside and out is amazing.
Thank you again!!!! ( RV. Net and all its followers are awesome)

I've got 2 or 3 grounds bolted to the camper tie down ring on the front drivers side. I assume they would ground through the tiedowns to the truck frame. I am the 2nd owner but I'm pretty sure it came from the factory like that.

That ground is for grounding the camper to earth when the jack foot is touching the ground.

My 2000 BF's main grounding point for the battery negative and AC ground is attached to the propane copper tubing that is located under the bed step, where the converter is.

I took the BMV-712 out of my AF 811 and am working on installing it in my 992.

In this video I talk about the shunt and the associated wiring to it.

Here's the video: BMV-712 in my AF 811

Back in the 90s I worked for Heart Interface. We had 4 different amp hour meters - very similar to the BMV-712.

I wrote a lot of tech documents about installing them. I also was on the phone all day helping people with questions on inverters / amp hour meter installation.

I always remember the "chassis ground" aspect of the installation instructions throwing everyone for a loop, because they had no idea where the "chassis ground" was, hence the reason I described it like I did above with regard to "there only being ONE cable on the battery negative post, and that cable goes to the shunt"

Once you have accomplished that, from a "chassis grounding standpoint", you're bases are covered, because essentially everything is connected the same as before, it's just that you now have a shunt inline.
