The IL Mobile home landlord tenant act is found in 765 ICLS Sec. 745. Here a couple sections that apply to your situation. I believe you get to break your lease, move, then charge landlord your moving costs. If you have to move to a more expensive park, you probably also get the extra rent reimbursed.
Good luck

(765 ILCS 745/21)
Sec. 21. Remedies, Tenants.
If the park owner fails to substantially conform to the lease agreement or fails to substantially comply with any code, statute, ordinance or regulation governing the operation of a mobile home park or the maintenance of the premises, the tenant may, on written notice to the park owner, terminate the lease and vacate the premises at any time during the first 30 days of occupancy. After the expiration of said 30 days the tenant may terminate the lease only if he has remained in possession in reliance upon the park owner's written promise to correct all or any part of the condition which would justify termination by the tenant under this Section.
Any condition which deprives the tenant of substantial benefit and enjoyment which the park owner shall fail to remedy within 30 days after having received notice in writing of such condition shall constitute grounds for the tenant to terminate the lease and vacate the premises. No such notice shall be required where the condition renders the mobile home uninhabitable or poses an imminent threat to the health, welfare and safety of any occupant.
If such condition was proximately caused by the willful or negligent act or omission of the park owner, the tenant may recover any damages sustained as a result of the condition including, but not limited to, reasonable expenditures necessary to obtain adequate substitute housing while the mobile home is uninhabitable.
The tenant may sue to enforce all Sections of this Act and the court may award damages or grant any injunctive or other relief.
