Injured and Homeless: RV Needed for a place to live

Raising money to get an RV to live in:

Im trying to find a semi decent RV that I can live in, come spring I have to find a place to go, I cant afford a house or rent. I have a cat so I would like to try and find a medium ish size so she has some room to live.

Long story short, I lost my job after a back injury and am still waiting on surgery, Im hoping I can get my surgery soon, go through recovery and return to work as soon as I can, but I know it wont be before spring. I would honestly live in the RV for a few years until I could possibly get a place.

The money would be used to:

1) Purchase the RV

2) Get solar panels

3) Use the rest of the money to put twords a car/truck that would be able to haul the bed if its not one of the motorized RVs

I know 55,000 is a lot of money, but spread between the three things it makes sense and I know some people might say put this twords a house but the area I live, 55k would get you a house thats falling apart and barley cover anything, (55k would only cover the down payment and fees) plus all the fees with buying a house and utilities. I know with my back injury and after surgery I wont be able to do it all alone with a house. Maybe someday, but this will give a place to stay until then
