LED Wall Pack for RV Carport

I’m getting ready to install some lighting in a metal building made for RV parking. The building is 18’ wide x 55’ long with 14’ tall walls. I originally planned to go with the UFO style lights, but the outlets and lights will be roughly 16’ off the floor at the peak, so very difficult to work with.

I’m considering using some of the smaller LED wall packs because they will keep easier to install without a super tall ladder or scissor lift. I figure I could mount them approximately 12’ high fairly easily. The problem is that I can’t find anyone who has done this before. That make me wonder if I’m overlooking something by going with the wall packs.

Does anyone have any input on this?
