Much will depend on just how clear the beer was when you kegged it.
If you gave the beer a solid cold-crash and racked above the sediment, there's likely not a lot of sediment in the keg, so the consequences of transport wrt going all cloudy should be minimal.
Of course you can skew the odds in your favor by keeping the keg cold (colder the better) and upright for the trip. I've taken kegs down to my oldest sons home five hours away without them clouding up. I stick them in kitchen trash bins with plenty of ice, wrapped in a sleeping bag and stood up on the floor behind the front seats for the ride down...
Cheers!
