Hello,

Thank you for all of the concerns, comments, and advice.

As has been suggested, I have decided to use 4 front stakes to hold a
rock shield cloth.

There is no concern about trailer load and the trailer suspension.  The
car is within the load specifications of the trailer and I check
the tires frequently when towing.

There is also no issue about tongue weight.  I designed specific Isetta
securing wheel chocks on the trailer to meet the trailer tongue weight
specifications.  Wheel guides are part of the trailer customization and
lock the car in position.

I have hauled the car long distances before on this trailer without
incident.  This was before the car was restored, so I was not as
concerned about rocks as I am now.

And, it's a 1958 US import Isetta with 4 wheels.

Thanks again for all of your help,
Mike
