Its interesting how different countries have different philosophies to
towing.
A few years ago I broke down in rural western australia and needed a 50 mile
tow for a landcruiser troopcarrier.
they towed it with a toyota tacoma and a flatbed trailer (btw a towing
arrangement for the much heavier landcruiser that is common in australia, I
saw a couple of these being towed out this way for a forty mile rough 4wd
track with fifteen river crossings)
But to my surprise, they did not strap the Landcruiser down onto the
trailer. Just put it in gear and handbrake.
I questioned the tow truck driver about that, who said that he doesnt want
the trailer and tow vehicle to get into an accident if the towed Landcruiser
"goes".
I guess thats one way of limiting risk... I cannot imagine though that they
did that with the Landies on the 4wd track, since there was too much tilting
involved there to get away without strapping down.
