Veteran in need of help

I just "turned" 70 (SEVENTY!!!! Yikes!!!). Although, during this very hard time I am going through, I have aged both inside and outwardly in appearance, I still do not "look" my age. When I did a GoFundMe some time ago, I had some problems. Some people did not believe I was on the level because I noted that I am a Vietnam Era Veteran. They thought I looked too young to be a Veteran of the Vietnam Era. It was difficult enough for me to do the GoFundMe. I have had a few Fb friends suggest that I do a GoFundMe again. The situation I am in is more expensive than people think or realize. I am learning so much in the process. My financial situation has been stagnant. I have not been able to gain any ground to get the funds I need in order to get a decent place to live. I still have most of the original donations that people have given to me, but, as I have stated before, I just haven't been able to increase the amount because of the expensive lifestyle of being homeless. All that said, an opportunity has presented itself and I need your help to get that chance. I was able to strike an agreement to get me out of a car and into a motorhome (RV) at a decent price. He agreed to accept my offer on his $12,000 final price and do payments on the condition that I am able to come up with a $3,000 down payment. I was able to save an additional $730 to add towards the$1,270 that I got from the GoFundMe. Thank you to those who have contributed towards helping me. Because of this, I was able to put $2,000 down as earnest money towards the motorhome and tie it down to prevent from losing it to anyone else. At the same time, it puts me at very low funds for living expenses.  I actually have a chance to get out of this situation and I need your help, my Facebook friends. There are things that need repair such as the microwave, 2 electric outlets, and replacement of 2 tires. There are other minor repairs. The Registration has been on hold for one year (non-operational) which must be paid along with the new Registration and transfer and other related DMV required fees such as Smog, etc. There is also insurance.  That said, it is mechanically solid and runs well. Please share this and donate towards helping this homeless veteran step out of homelessness.

Please have it in your heart to help me. May our God count this as a future blessing for you. "Blessed are the merciful......"
