Repairs to my home (Travel Trailer)

I hope that I can do this correctly. I have never tried to get help though a social platform.
My park model RV has just recently become my only housing option.
I was living in a nice little rental in Benton City until 6 weeks ago when the owners informed me that they were selling and moving out of state. I had purchased the park model in April with the plan of doing a repair/remodel on it next year and making it my residence by end of next summer. Unfortunately that plan had to be revised because of having to move from the rental. 
I have been in my trailer for just over 2 weeks and was doing my best to fix the small issues such as plumbing. The rain last week proved to be the catalyst for a more pressing issue. When I bought the trailer I was told that the slide had leaked but that they had taken care of the issue. I had chosen not to extend the slide in case the issue had not been addressed. Not only had it not been repaired but even without being extended it leaks. I can a professional repairman who came an assessed the situation yesterday. Not only is the slide damaged beyond repair but there is black mold in the walls.
I very much need to have the slide removed and I am having a wall put up instead...I am willing to forego space for warm and health safety.
I will appreciate any help that is provided me. Even prayers.
This could be a miserable cold and possibly unhealthy winter for me if I leave the slide as part of the trailer. 
Thank you for reading this even if you can't help I appreciate you taking the time to read this.
Blessings to you.
