I watched a mate build his pride and joy roof rack to  suit  the  Troop Carrier.  Without doubt  it was an art form when completed  and looked a million dollars  all fitted and loaded  for the trip north out of Townsville.  I and others had suggested to make a continuous foot running the full length of the gutter mount, No way the feet are OK was the last of that debate ,

Made it to the top and on the return leg along the tele line   we stopped for a cool drink , every one piled out of their rigs  expect the mate with the DIY roof rack .

The constant vibration  had caused the SMALL feet to  wear through the gutter rail letting the roof rack settle onto the roof  and  the legs over the door frames so nothing could be opened .

I'm sorry I don't have any  photos as we laughed so much I forgot to take any  of him and the wife and kids getting out through the windows .  The rack is somewhere along the track  as a ladder against a tree for the kids to play on  .

So if building or buying  a rack take note of the position the feet bare down on and take the hint to distribute  the  weight  across the largest surface area you can  and use rubber gutter guard to absorb the vibration .

Had the battery given up as well then no windows could have  been  opened  , What next   I hate to think
