We have 2 dogs (micro goldendoodles) and they do great. RV parks are just dog parks that allow RV's! They are crate trained so stay in their crates while we are out without them. No barking. I have a wifi thermometer to monitor temp inside the RV when it is hot outside. Never came across a RV park that didn't allow unattended pets inside the RV. Ones that say this are typically referring to leaving them unattended outside.
If you love dogs, get a dog. If you don't, then don't for the sake of the animal.
