I purchased a new Keystone Dutchman Astoria RV 3553MBP on October 23, 2021. The RV has toxic air quality which caused me to have headaches, blurred vision, no balance, confusion, sleepiness, & vomiting. I was taken by ambulance and admitted to the hospital for a couple of days. Carbon monoxide levels were elevated. RV test showed poor air quality & formaldehyde. I cannot live in my new RV because of the air quality. I have been trying to work with the dealer Blue Dog RV in Pasco, WA to get a replacement RV, but to no avail and Keystone RV has informed us to communicate with their lawyers. I paid for an extended warranty and nothing is being done to make this purchase right. There are many complaints/classaction lawsuits against the RV manufacturer Keystone for poor air quality and unacceptable customer service. How can this company get away with selling toxic RV's? Consumers must be protected from unscrupulous manufacturers and dealers selling defective RV's.
