I've experienced this, first hand. Unfortunately, NYC has two things that make a haven for rats: 1) A giant, heated, rat hotel that is mainly not disturbed--the subway system 2) The typical refuse pickup system where trash bags are thrown on the curb forming a rat smorgasbord.
When visiting my Daughter in Brooklyn, I went out on the steps to have a cigarette on trash pickup night. I was surprised by a rat the size of a small terrier. Observation showed that they were coming up from the subway ventilation shafts and it was only a short sprint to a pile of trash waiting to be picked up.
For RV's and rodent deterrents, it seems the best is absolutely sealing any possible entrance with a material that can't be chewed. Traps and cats are not 100% but can aid in diminishing the population. I would guess snakes could also be used but are less efficient than a cat. My cat leaves rodent trophies in the same spot, mostly uneaten. She does occasionally have mouse tartare but I feed her too well.
Good luck to those in a battle with rodents.
