1998 Van Con GMC Savana

The dealer sells half million dollar camper Vans but sold me a 1998 GMC Coachmen Savana.He has wrong year on all documents my insurance says! The urgent safety issue to my life and safety to others on national roads is that I CANNOT drive the van/ home at ALL (the delears technician inspected the van QUICKLY and left engine light still on,I said I did NOT want van if they would not find the problem but forced to take van,I called cops. I have mental disability this is my only car that less than 2 months after I bought it,I CANNOT DRIVE this van without DEADLY CONSEQUENCES to me and other drivers/passengers on national/state highways.The carbon monoxide began leaking out immediately after I bought and then I noticed the GAS LEAKING FROM Tailpipe within first month and told state park and Texas DMV said make complaint on computer. I have phone only but now in January 10,2022 It was cold I ran camper and I had videotaped the leak in December 2021 I bought it November 13,2021(Stahman Walmart ing lot,I saw huge spill when I get out of back where I SLEEP and my dog.The carbon monoxide is enough to kill us both but on January 4,2022 in Walmart lot huge spill as open door I stepped in it.I had ran van for 45 minutes I knew a small leak in December, I told DMV and state park they seemed to care because DMV ignored my emails since December but nobody will help in state of Texas. This is a SEVERE DANGER to other drivers/ passengers, women children pets.. on the ROADS NOT just my life and my dogs that nobody cares about. We now have SERIOUS situation. I CANNOT drive off this lot back on state/ national roads without SERIOUSLY ENDANGERING MYSELF and other DRIVERS/ passenges.This leak is NO longer just a little danger now GROWN to a huge leak, a 1/2 tank of gas LEAKED OUT on Walmart lot in Victoria,Tx.I am writing to please help me not die or harm kill others with this vehicle that SHOULD not be DRIVEN.This is my home/car, I lost my 2013 truck I traded and large amount of cash!
