Re: Rear Door Load Capacity . . .
I have a 2007 FJ, which is before the backup camera, which was first introduced in 2008. Also, the spare tire cover, which contains the camera, was an option on the 2007. I didn't opt for the spare tire cover. Hence, a bicycle mount attached to the rear tire doesn't require doing something with the camera.
This brings me to my point. I have a Yakima "SpareTime" bicycle mount attached to the spare tire mount on the rear door. I would guess the mount and two bicycles weigh less than 100 pounds.
Water weighs more than gasoline, so using water's weight of 8.34 pounds per gallon times 10 gallons, or 83 pounds. Adding 10 pounds for two jerry cans and 50 pounds for the structural frame to hold everything, brings the total weight to about 150 pounds.
I haven't experienced any problems carrying bicycles, although about 50% of what you want to do. However, I think your concept won't be an issue either. Just exercise care when opening and closing the rear door. For instance I do not allow the rear door to freely swing open when parked on a hill with the front end pointed up the hill. I wouldn't want the door, having extra weight, freely swing open to be abruptly stopped by the door strut.
Maybe someone on the forum has performed the modification you are looking for.
