What is the cost comparison between this ladder thingie, and say a sub tank? I'm thinking a subtank would be cheaper, the engineering is already done by Toyota, and if you just have to have a rear ladder it could be smaller and less bulky. I also know that it isn't hard to scramble up onto the roof rack just using the bumper and spare tire. I've done that many times.
Ok...now that Andy has broached the subject I'll cast my vote for somebody importing/sourcing 105/100 dual filler necks and a aux tank "kit". Ideally for me 15-20 gallons would be ideal or whatever capacity for maximum gallons without hanging down.
Just what you need huh Christo...more ideas
