I've used the liveries with my own stuff when I am going out with a group that is renting. It works out fine and is fairly cheap. If I am going out alone or with others who own I never use the liveries but use two trucks or paddle back to where we started from.
Here is a trick I've done:
When going alone over a long distance I will have my wife follow me to the ending point and drop her car off. Then she gets in my truck and we both drive to the start. Then i unload my canoe or kayak and she drives my truck back to her car (at the end point), she hides my keys where I know where they are and then she leaves my truck and takes off in her car with no further obligation.
this works fairly well, doesn't take up much of her time and I have a truck waiting at my end point.
