Wanted motorhome - $5,000 (Los Angeles)

I am looking for someone who has a motorhome in decent condition that is willing to sell it with a low down and payments.
My credit is not the best but I have a guaranteed income monthly.
I am trying to buy one to live in for me and my small dog.
I will never be able to own a home so this is the closest I can get to something to call my own home.
