Thanks for all the input. Yes, you are all correct in suggesting a tax pro for this. Also, I feel that forming an LLC for this venture makes sense also. The real reason I asked the question was to determine how much savings we might get by using an RV rather than staying in hotels/motels. First, I like living in our own dirt and clutter...secondly living on the road eating in restaurants is bad for my health. Guess it really does not make a big difference about the tax write off thing because it's really about living the way we want to on the road.
Again, thanks for all the input.
