My RV was stolen, burnt & destroyed

On April 22 I was very shocked to find out my RV was  stolen from where it was parked in N. Hollywood.   I rely on the RV to sleep in when I am not staying over night working as a caregiver, pet sitter and house sitter.   3 weeks later an auto detective left me a message that it was recovered burnt in Arleta about 8.5 miles away and was taken to the local tow yard.   I heard the word burnt but did not expect to see the TOTAL DESTRUCTION of the vehicle I really counted on plus ALL MY BELONGINGS such as my clothing, shoes,  pc, dvd player,  hats,  scrapbooks,  documents,  toiletries, food etc that were inside.  EVERYTHING TOTALLY GONE -  total destruction.  Even my friend's ashes which I was saving.    Being the victim of a fire is horrifying.   A policeman speculated that the thieves were cooking meth and started a fire but because of the heat  of the fire they could not take fingerprints.   It's been hard to fathom that this took place and extremely depressing.   I really need your help to replace everything I've lost.  I was only insured for liability so I will not get anything from the insurance company.   Please help me.   Thank you very much.   I'm a good person and have done a lot of charity work and believe in paying it forward.  Thank you.
