Hi TH,
To answer your question more seriously; no personal experience mind you. I’m guessing you’re thinking of trailering down to Conclave? I’ve heard concerns about ruining the transmission on long tows due to lubrication problems. Disconnecting the drive shaft would prevent that. I’ve also heard people say they’ve trailered their Healey with no ill effect. I’d probably disconnect the shaft for peace of mind since rebuilds aren’t that cheap. Not sure what route you’re thinking of taking, but the 5 Fwy, South of downtown Los Angeles is pretty brutal. Lots of potholes and uneven pavement to bottom the car out on.
