11/4/20–Grand Design RVeBay logo informs THOR Ind. of three incidents involving Winntec Model 6020 regulators, where the regulators were suspected as the cause of fires. The Thor companies reviewed the issue internally and found no issues with these regulators at that time.

 

12/4/20–KZ RV informs THOR Ind. of two issues under investigation with the same suspect regulators.

 

12/22/20–Grand Design performs lab analysis on two failed regulators and finds they contain an oily substance inside. There is a belief that the oily substance is machining oil from a manufacturing process.

3/16/21–Lab analysis performed on six regulators from Grand Design, including one exemplar and one from KZ RV. In the lab setting, the KZ RV regulator operated within allowable parameters, although it contained the same oily residue seen on the field samples.

5/10/21–Safety Committee Meetings conducted at KZ RV, KeystoneeBay logo RV and JaycoeBay logo RV, to update them on regulator investigation. All committees request further investigation of specific claims and confirmation of Exponent findings.
