To throw a wrench into things, if we were talking about real property/structures that were being short term rented, it's possible/likely that your depreciation period would be 39 years, not 27.5.However, a vehicle - which is what an RV is, regardless of how you're using it - is 5 year property.

Either way, if your real question is whether or not I can "afford" to buy another rental with this strategy going on the answer is yes.
