I recently originated a thread pertaining to a campground operator telling us that Florida law prohibited leaving pets unattended in RVs. I just returned from Florida and while I was there I contacted...
What the Sheriff told you is correct...there is no law against leaving a pet in an RV.

Doing this is against the law in most states.
