My wife and I do the majority of our travel for pleasure, however, I also use the RV for traveling to facilities for business. Since our house is noisy with kids and dogs, I also use the RV as an office when we are not on the road. I am not looking for the IRS to audit me as a business owner, so am looking for what can and can not be declared as a deduction and what documentation is required. Many Thanks as this is my first post. Andy
