Can you run a 220v A/C unit off a 50 amp service?
Can you run a 220v A/C unit off a 50 amp service? I want to install a mini split unit and Im totally confused about "two hot feeds- split main breaker box" Thanks for responses.

You can if there is 2 phase electricity at the plug (A and B), BUT I think both phases must match, must have the same load on them and the same ability to supply. If it were just you powering off the breaker box then no problem, but who know how many campers are powering off only one phase of the box and not the other? You cannot control that. The first response is saying this, but without much of a warning flag waiving.
Great likelihood of damage to your AC unit. Cheaper to get the 120 version.
As has been said before, lots of " 50 " amp service in campgrounds were installed on the cheap so you will have 120 from ea hot leg to neutral but not 240 hot to hot.
Personally, I only have installed a couple hundred of these units and I haven't seen one that I believe would hold up for the long haul attached to a rv traveling constantly. Others may have a different experience.
