^^. Glad to hear more confirmation of my thoughts. That the 911 can be towed with out undue consequences . Thanks Bob!

I did post my question here because I recognize there is a lot of experience and diverse backgrounds to draw from. Sure some opinions come along too.
But ultimately the info I was looking for came to light also. Plus many good points to consider.

Just yesterday I went by a metal fab shop to get the brackets made to connect the tow bar to the bumper/receivers.

The last piece of the system is a rock Sheild to mount just in front of the car on the tow bar. The search continues. So far craigslist has come up with descent deal on the other components needed.
This Sheild plus the bra Todd offered should keep the road debris damage to a minimum.
Really stoked to think of heading to Colorado in mid April with the SC in tow . Heading to a classic airstream motorhome gathering near Colorado Springs, should be fun.
And close to Pikes Peak, just one of the drives I'm hoping to do with the SC.

Cheers Richard
