I have a hard time believing all this stuff in fact fits in your FJ LOL.
I think this stuff to me is not going to make camping any better in fact it would drive me nuts. I would loath getting up in the morning and packing. I'm not sure what camping or "expedition" trips are to you but most times its setting up camp in a different place each night and moving on early the next morning.
Your setup is like a house (& catalog) on wheels and that's not camping as most would class it. I'm not knocking you, if you are cool lugging that stuff all around then great but wow that's got to weigh a lot!
I would skip the tent heater and mat and just get a warmer bag.
