We purchased a Winnebago One 30RE and really like the layout. Only problem was we couldn't stay in it because of gassing from the materials. After wiping down everything with Water and Vinegar, running an Air Purifier with 4 filters including a VOC, running a humidifier, buying some plants rated high for formaldehyde removal, putting out Baking Soda, and even trying cut onions I think we may have overcome the problem. When I talked to the Winnebago rep he also said to try baking the RV which we did. He said if all those don't work we may have to try some voodoo.
