If you are going to keep a spead sheet of what your toy costs you, per mile, camping etc, why bother is my question? it is what it is and the numbers will only make you start thinking, is this really worth it?, enjoy your toy , I never keep a spread sheet, it will make me sick, I do keep receipts and keep them, only to have them, I really do not want to know the real cost of fuel, etc for a trip I just enjoy the journey, the cost is not going to change, you still have to pay the bills. But then this just me, I am not one to fret over every penny unless I can deduct it for tax reasons.
I have speny my money on RV's boats, airplanes and women, the rest was wasted.
Be safe out there and have fun, Fins UP!
