RV or hotel stay as business expense?

Hi, 

We run an investment/rental business with multiple properties. This includes renting out our primary residence as an Airbnb occasionally (greater than 15 days/year). In order to offset this, we bought an RV to live in when our house is rented, and we occasionally will stay in a cheap hotel.  What I'm wondering is, is any of this deductible as part of our business - the price/maintenance of the RV or the hotel stays?

 

Thanks,

Jonathan
