Good food for thought. I typically do weekend camping trips and use a portable jumper/air compressor unit for my charging needs. Has usb outlets and a 12v outlet. Charges off 12v while driving. Works good enough for my needs. Total cost was under $100

Good morning Jason thanks for sharing this very well done on explaining one thing I would say emphasize when you’re doing your own wiring on your vehicle is the Take Your Time stay with certain colors for install label your wires and protect the wire of where you’re putting it so it doesn’t get pinched Also think about emergency shut off circuit, breakers and fuses and one more thing if you do not feel comfortable doing the work get help or take it to a professional shop to have the wiring done the last thing you want to have is an electrical fire inside your rig

Thanks, this is exactly what I needed.

Interesting, thanks. I don't use the Xterra battery for anything else. The offroad-ish trailer has its battery which only powers its lights and fan. The deep cycle trailer battery charges while going down the road. Inside the trailer, I have Jackery 500 to charge phone, electronic reader, camera battery, or maybe a 12 volt throw. I've never run it down. In the back of the Xterra is the fridge and a 600 Rockpals. I used to have Zamp solar, but they're a bit big and heavy. So I have a couple folding 100 Rockpals solar which can hook together. I haven't used the solar in bad weather, but have used them in semi-shade, and it keeps up pretty well. So far, I haven't needed the latest and greatest. When I leave the vehicle to go for a stroll with the dog, I just unplug the solar so I can close the back and leave it to keep the fridge going (locking the vehicle). It seems like a lot of extra stuff to take, but it works. I could always just go back to using a cooler which sits on the front of the trailer--life was simpler, but if I don't want to run out of ice...

Do you have a video on how you install the solar panel?
