I should have known!Dometic fridge and a home made battery pack.
Awesome work here!Warning: Geeky post
Situation: The cigarette receptacle/power outlet in the back cargo area of the 4R has a significant voltage drop under full load. The gauge of the OEM wires is too small to handle the current of a significant (under 10A) load. Shame on you Toyota. Works OK if all you are doing is charging your phone and powering your GPS display. The five outlets are powered by one 15 Amp fuse. The typical max current for an outlet is 10 Amps or 120 Watts (10A x 12V = 120W). So, full load on all 5 outlets would be 50 Amps.
Experience: While trying to run the fridge and charge the fridge's battery (total current about 8 Amps) the voltage dropped to the point the fridge (set on the lowest cutout voltage) shut down. Disappointing.
Fix: Added a separate power wire, a relay and a switch. The relay coil is powered by the OEM outlet circuit. Key on = relay on. The relay contacts (switch) are wired to the battery and the rear outlet. Relay on = outlet powered. I also added a switch (with a NASA style guard) to power the outlet with the key off.
Result: Outlet under full load, minimal voltage drop.

Relay behind outlet panel, next to inverter. Replaced the wires to the outlet with larger gauge wires.

Definitely the best color combo out thereI picked up another vehicle, so that I could work on my other vehicles in peace and quiet. Something that can just be driven reliably, and can save the LX470 for the fun trips. Of course it can’t be that easy, the vehicle isn’t completely perfect (178,000 miles), so I’ll have to start working out the quirks. It’s certainly roadworthy, as you’d expect of any LS (picked it up in Naples, FL on Friday).
I present to you a 2005 LS430. I like to think that it’s the Land Cruiser equivalent of sedans.

more info on home made battery pack? you mean similar to a jackery/bluetti?Dometic fridge and a home made battery pack.
I have access to Autocheck. Not exactly the same, but pretty close. Feel free to PM the VIN if you'd like.Anyone on here have one of those unlimited Carfax accounts and can save me $40? I'm looking at a 3/4 ton Suburban and want to run the VIN.
These batteries were made just for the fridge, so no misc extras and much less expensive than the commercially available battery packs. I have a 50A Anderson connector in the back of the 4R to power stuff. I use that to power the fridge and charge the large battery. I also have a power cable for the fridge with an Anderson connector instead of the cig plug. I kept the cig plugs so I could use the fridge and batts in someone else's (wife's) SUV.more info on home made battery pack? you mean similar to a jackery/bluetti?
i was having the same issues charging the portable battery from the rear outlet. I ended up with this goal zero charger to get it to work. it works for now but i am thinking i may need a solar panel or something to have the fridge run for a longer time.
How does this happen? Just got too close to the edge of the road?
Usually things like this happen when a driver is not paying attention to the road. Believe me, the scenery out in CO is so dramatic it's easy to let your mind wander from the most important task at hand. When we were out there a few years ago a guy from the northwest drove off the Cumberland pass road in an 80, demoed the truck and I think one person was killed. We had driven over that pass a few days earlier. Not dangerous if you're paying attention to your driving!How does this happen? Just got too close to the edge of the road?
