The only outside party that gets a portion of the rent is Square, whenever someone pays with a credit card. 

Make sure your tenants are making other arrangements, either on their own or through the Red Cross (their Renter's insurance should provide them lodging, and, if they caused the fire, might handle some/all of the restoration).

Find Brandon's videos on YouTube for the "four square" method of analyzing homes and practice.

Are there specific things you ask or look for; or maybe red flags to stay away from?

What size square foot RV's are you buying?  

In your scenario, you could breakdown square footage and divide out based on that and the number of people. 

(I once split a glass of red wine all over the beautiful white sheets in a hotel!) 

And then I used Brandon Turner's Four-Square method to analyze the property.Some observations: 1.

Manufactured home floor space can not be smaller than 400 square feet and must be classified as real estate.The only manufactured homes that may be classified as real estate or "real property" are those which have a permanent foundation built to FHA standards.

If you expanded your search to three bedroom homes, at a similar square footage, than you may be able to add a closet or a window to a space creating an additional bedroom (if the septic/sewer supported it).
