I have encountered no issues regarding clearance but it is a 'challenge' to load as there is no lateral 'forgiveness' regarding the ratchet/winches so if you are off center on the basket straps it is down the ramps and try again.
Perhaps it is caused by DW's directions
but loading it is troublesome for us. The older Acmes used to allow the winches to slide in order to get centered on the tires like a Master Tow but they are stationary now.
I did get a key cut that will not start the car but allows the steering to stay unlocked (it was expensive but not as expensive as the programmed key) as I did not want anyone to be able to drive it away if we left it unattended and on the dolly.
I changed the safety chain arrangement because the safety chains would bounce out of the banjos on a rough road. I ran a length of chain across the dolly through the banjos and connected the safety chains via a removeable link,
It is a fun car to drive but do make sure you keep the roof seals conditioned with Krytox as leaks on this vehicle could cause catastrophic problems
