Cargo conversion, ramp door vs. barn doors

Just ordered a cargo trailer to convert into a toy hauler
and like most I ordered the ramp door cause it just seems to make sense and because that's just what everyone does. So I need some opinions. I will be loading ATV's and/or my Wildcat SxS. The ramp seems to be the best choice but I could easily load with a set of ramps to accomplish the same thing.
Reasons for now thinking barn doors would be a smarter choice albeit a bit harder to use:
1. Width of opening, ordered a 7' wide, the ramp uses more space than doors. SxS is 67" as it sits now.
2. I could add two small slider windows with screens in the doors for cross flow ventilation while camping and not using the AC.
3. Maybe most importantly, I could use an inside locking mechanism when we are camping and use this as an extra emergency exit.
I have a few days to decide before they start building my trailer, so, is it worth dealing with a set of light weight ramps in exchange for the ramp door?
