Tiny homes in RV parks

Are these generally able to be parked here?
I'm in IL.
I was also recently told trailer parks are different from rv parks. Is that true?
Also, I've been searching for rv parks in IL that allow long term stays and have only found one so far, which is insane. And it's very expensive. So if anyone knows of such a thing please let me know.

Have you considered the laws may be different for RV  and long term accommodation.

I worked for a guy that bought an RV park in Chicago, Illinois.

I don't know if he is still there though he offered monthly rentals.

Almost every RV Park I have worked for offered Monthly rentals.

Is your tiny house on wheels?  If not that might be a problems.

And yes, the monthly rentals now days are expensive.  Almost like renting a house.

I've so far looked at (online) about 125 mobile home parks and contacted every one. Only one so far allows tiny homes.

And I thought tiny homes were not allowed in chicago?

It seems Yorkville allows them on a foundation. Part of Yorkville looks to be rural so that's good. Is anyone familiar w/Yorkville in regard to these? That would be somewhat close to my father, about 45 min away.

Thanks so much for your help. So far FB, reddit have been zero help. I really feel alone w/all this.
