To me is boils down to a matter of "what do I want to spend". On my first two RVs (fivers) I had them hard wired in. Since I had RV techs do the work it was more than twice the expense. On my MH I am just using the external plug in which gives me the same protection but just less cost.
I have a lock box on it but I guess someone could still steal it if they wanted to bad enough, that would be the only down side.
