tax writeoffs for full timers who work from road

thanks to everyone who has taken the time to answer my question. to be clear, i was looking for ideas, not legal advice. interestingly, my tax guy is less informed about this issue than many of you are. I think my main take-away is that i will not be deducting any rv parking fees, fuel, maintenance, etc, with the exception of a specific destination we visit solely for business. in that case, we rent a car, pay for client lunches, event fees, and an rv park. i will deduct those.
