I think you making service calls to different areas during days AND nights will be good to include as well as if you carry cash/checks deposits also. This is just me and my opinion but if RI is a "shall issue" state, which it must be, I wouldn't make a huge deal in the letter of it being your right under the 2A, we all know it is your right, but you never know, they may think your just being a smart aleck or something. Just the way some people are, esp the way the politics are going these days. I think relating your request to your personal protection related to travel/business, etc might be good. Good luck.
