Nitrogen as mentioned before, is used because it will not expand like ambient air when heated. On a trailer that experiences a lot of sidewall flex this will keep the tire psi from increasing, which makes the ride harsher. Trailers typically have terrible suspension, very little travel, so the tire is a big part of the suspension system.
On RV's that are carrying a lot of weight a tire can heat up a lot and I have seen psi regularly go from 80 to 140. With Nitrogen this jump would be much less. I have seen tires blow up due to the increased psi, and a 140 psi tire blowing up will do some damage for sure.
As tires age, even before their 6 year due date, they tolerate changes in psi less and less.
I am not advocating using N, but this is a real benefit.
Racing uses it and they use nitrogen in their air shocks for the same reason. Shocks get very hot when used, so the N will keep psi more stable.
For campers it is a bit overkill, but if I had a choice I would take N every time, so leave it in there as long as possible
