somehow I never liked the grid beam system... but the tote gote is a true gem
you move it wherever it makes sense.
my emphasis on lightness... well, my maxim is: "the less stuff you have, the less you have to take care about stuff" and reducing the demand for horsepower is always a good thing - I think. So everything I do not add to a vehicle gains me agility and every thing i have to add, I wanna have it as lightweight as possible altho not at any cost.
I did backpacking and mountain biking for years. During that time I figured with how few things one can survive. Now you are probably asking: "why a ford van then?", right? the answer is, that I'm gonna have customers sitting in the vehicle quite often - and I just can't manage that in a toyota tacoma (which I would choose if i would be all alone all he time).
