Anybody no if you can run a 50 amp power former on a 30 amp service or do you need one for each service

yes you can
you are still only one leg of the 50amp
still only have 30amp service, a solid 30amp,
and you do NOT need to use the autoFormer when using a 30amp rv on a 50amp service
however if its hardwired, just use a 50 male to 30amp female, it won't hurt any thing
Just because you are using 50 amp service for a 30 amp rv does not mean that the full 120 volts are there. I always test both plugs (30 & 50) to see if either has more voltage and rarely find a difference. So if the voltage is low on the 50 amp circuit it would help to have an autoformer.
