Just a little oddity... If you muster out with a vehicle, you have a max of a 5000cr limit. Unfortunately, none of the stock vehicles fall lower than that. how have others dealt with this? Create a vehicle for them? Or something else?
You can get a Jeep, that's somewhere around 2500cr. I think if you can get a multi-million credit stake in a starship for a mustering out roll, allowing the players to get an ATV or even an air/raft ain't unreasonable.
