^^^^^^^Vary well put.
I will always accept the gas money. If I am pulling you around the lake then you can help chip in on gas. Especially if you are a regular. If you didn't own a truck and asked me to drive half way across the state and haul something for you then I would expect for you to pay for the gas in my truck. To me you can either help cover the gas for riding on and behind the boat all day or take on the full expense of owning a boat. I bet most people would find it better to just chip in the 10 bucks on gas compared to having all the other work and expenses.
