[Shop-talk] Enclosed car trailer

[Mike Rambour]

  and when you get lucky and I mean really lucky, the car rolls off the 
trailer on the freeway offramp and comes to a stop with minimal 
damage...a few hundred yards earlier I would have been to 60, instead I 
was doing 10mph, like I said lucky.  This was with the chassis strapped 
down tight, but I guess not tight enough since a downward bounce allowed 
the hooks to come loose and the straps came off.


  After that incident, I got the wheel basket straps, moved the D-rings 
to where they needed to be and never strapped down the chassis again.  
Let the chassis bounce all it wants, keep the wheels locked down and the 
car will stay.  Maybe even better for the car since the cars suspension 
is still able to freely move.

When you are hauling a car like a TR with a stiff, overdamped suspension there is little secondary bouncing.  If you are hauling a 70's vintage Cadillac, on the other hand...
