Try stopping in a hurry on a slippery road :) The brakes definatly take some getting used to, trouble is other people rarely leave you the luxury of enough space.
I don't know what you mean about series landies not having load space, there is more room than in a Volvo in an LWB albeit if you have indivisible loads like wardrobes and filing cabinets the Volvo is best.
As for pathetically low towing limits? Really I was not aware of that, maybe not the 4 tons of a defender as plated, but certainly more than any conventional car on the road. To be honest though I don't think anyone is ever going to challenge what you tow behind a landie, unless it is the flying scotsman on a low loader.
