You should always disconnect the negative cable first - and conversely, attach the negative cable last.

Yep, yep, that's generally the way I look at it. Prevent sparks where possible, so I always disconnect the negative cable before ever putting a wrench on the positive cable clamp.... That said, if you're working on a boat that's sitting in the water, you've always got a negative connection "everywhere" including standing on the dock, because the boat is in the water, making the connection "always".... So, while I'm in agreement with you (when it comes to working on RV's on land) some people tend to apply the same conditions to every battery in every condition in every situation.... Hence, the + battery cable argument keeps surfacing....
In my Ford owner's manuals for every Ford I've owned, the section concerning "long term storage" states to disconnect the negative battery terminal. And, in most of the "caution statements" related to the battery, that same, "Remove the negative battery cable, first" keeps appearing....
I'm in complete agreement with you, just giving what I think is "the other side of the argument"... My battery cutoff switch is connected to the negative battery terminal/cable.....
