I have an easy-up system--the frame fits on a dolly, when get to my destination I can lift the frame off & hang it on a stall and use the dolly to move hay bales, etc. I have a muck bucket attachment that also fits on the dolly so the whole thing is multi use. I just love it--got it 20 years ago and it has always been trouble free & still looks good.
I also have this thingie, which I cannot remember the name of, that is basically a loop with a solid metal piece at the end (like a T, with the top part of the T being the metal thing, and an adjustable chain at the other end). You loop the chain around something solid and then put the saddle on the nylon loop - the end of the T keeps it from sliding off. It acts like a saddle rack, and when you aren't using it, it just hangs there. Pretty neat.

I can't remember exactly. But I went to a show where they had metal stall front with the grates on top and the rack fit. I think it was my daughter's show where it didn't fit. They have an all grate front and I couldn't hang it from there. I also went somewhere where Ithink they had the portable stalls and it hung so low that the saddle wouldn't stay on. But it works great at home and on the trailer!
I have seen the easy up and like it, but I am a little height challenged and don't know if it would really work for me. I like tack stalls and can sometimes split with a friend because I won't pay for one just for me. But they are not always available. So, still looking for the perfect solution.
I don't want a saddle cart because often there just isn't enough room in the aisle and I have seen them blow over. Not good.
