SPARE WHEEL CARRIER 100 SERIES

Yes there is no way the standard door will take the weight of a tyre and wheel without extensive reinforcing inside the door. Then you will have to reinforce the pillar and the door hinges.
Given that an improperly designed bumper mount carrier will fail the door wouldn't last long at all.
Reminds me of the troopy owner we came across years ago west of Windorah, he had pulled up to make a cuppa and walked around the back of his truck to see four big holes in the door skin and no spare tyre!
He had just bought the vehicle secondhand from a caryard and they had bolted the tojo tyre bracket straight onto the door skin of an unreinforced rear door instead of the proper door with all the internal bracing.
We hadn't seen his spare and bracket on the road either!

JTW, definately don't try mounting it straight to the door. My rear doors are sagged and rub at the top at times and they don't have anything hanging off them. Shop around - I got my replacement rear bumber and rear wheel mount for $1400 brand new. I have seen a cheaper alternative that keeps the original bumper but mounts off the chassis somehow for around $500.

Try holding a spare wheel and shaking it. Then multiply this by about 1000 and you get an idea of the stresses involved. Putting a spare wheel on a door is a cheap way out for manufacturers and can be OK if you stay off corrigations etc. Even doors 'designed' to hold a spare can fail. BTW I found in my research that if you want two spares on the back - only the TJM one will accommodate the LHS barn door. Both Kaymar and ARB said theirs will not allow a LHS wheel.
What is really wrong with the spare underneath anyway?
