Diode Dynamics has them as well

Hi Jon. Yes, I could. One way is to disconnect the battery + wire at the junction box on the inside frame of the trailer, and tape over the terminal. The easiest and less risky way is to remove the fuse from the power distribution box. Is that what you were thinking? Thanks, Rick

Thanks, look like an easily accessible location; I could mount a fuse on the firewall. My truck only has the right side battery, so I think I may identify the 7 pin charge wire from the under hood power distribution and add a 30 amp off-on switch, so that I don’t’ have two charge sources from the truck, plus solar on the roof. Sound like a good ideas? Rick

How did you do the wiring at the 12 volt truck battery? Thanks

Good quality components with your setup. Lance used about 10 gauge wire from the solar controller on the curb side of the trailer, and it then connects to the battery master switch on the street side of the trailer. I can't see the wire and hence it would be a task to run heavier wire for an MPPT controller. Thanks for information on your wiring.

Great install using quality components. I have a Victron BMV-712 to monitor my batteries. It would be a logical step to add a Victron DC to DC converter. I suppose you ran wiring from your truck battery. I has been raining for a couple of days, and I did not look under the truck to run the wiring. What side did you run the wiring on? As I don't have an inverter and have 200 amps of batteries and 190 watt of solar, I would probably install the 18 amp version. My trailer came from the factory with a PWM solar controller, and would be challenging to run new wires for an MPPT controller. Thanks Rick

I reached out to Blue Seas and they don't recommend an ACR due to lead acid battery in truck and lithium in trailer. It was recommend that I install a DC to DC charger in place of an ACR.

Thanks Another JR. I had a Blue Seas ACR in my boat, as I had two batteries, and only a small alternator on the outboard. I wanted to ensure that I could start the main outboard after fishing, as draw from my fishfinder and radio. It did the job well. For our trailer, I have a roof mounted solar panel, and 2, 100 watt lithium batteries, so my interest is primarily on disconnecting power to the 7 pin plug when the truck is not running. A less costly solution is the continuous duty solenoid, but perhaps issues with hooking it up. Specs on the Blue Seas ACR indicates maximum current is 140 amps, but I believe a 170 amp alternator is standard on the gasser with a single battery. Thanks anyhow, I appreciate your response.

We tow a trailer with our 2021 GMC Sierra 2500 gasser. I read that the 7 pin trailer plug is always hot, even with truck engine not running. We had a continuous duty solenoid installed in our 2015 Chevy Silverado 3500 to cut power to the trailer plug when the ignition key was off. I would like to find the wire that goes from the power distribution centre to the trailer 12 volt, and another wire that I can use to trigger the solenoid to complete connection when key is energized. Has anyone done this on a later model truck? Thanks, Rick

We have the same hitch as Jettech1. We had a 3500HD when we bought the trailer, but now have a 2500HD. The dealer told us to use the hitch. Our travel trailer is 24 ft in length with a GVWR of 7500 lbs, and tongue weight may be 600 lbs. I might try towing without the sway bars to see how it handles. We have to back up a slight hill to park our trailer and need to disconnect the bars to do so anyhow.

Thanks Steve. Appreciate your quick response. Our truck is an SLE model, so perhaps no trimming, but I like that it would be higher up closer to the bumper. The front receiver on our 2015 3500 was lower and could hit the street, coming out of our driveway.

For our 2021 GMC 2500HD, it appears only Draw-Tite and Torklift offer front receivers. We have the off-road package on our truck. For anyone who has installed the Draw-Tite on their 2020+ trucks, do you need to remove the skid plate to install the hitch? Thanks

Sorry to take so long to respond. We live near Victoria, BC, Canada, home of GoPower. As such, we bought GoPower lithiums. We have easy access to service if we need it.

We have a 2021 2500 gasser. We have 2, 100 amp lithium batteries in our trailer. We also have a 190 watt solar panel. Last fall, camping in a forested area, and cool weather, we drew our lithium batteries down to about 60 percent of capacity. When we connected truck to head home, the alternator was putting out over 20 amps (I have a battery monitor). So, the factory alternator with stock wiring should take care of your battery needs.
