There is a whistling sound coming from the front of my 2018 Thor Ace30.4 which seems likely related to the front grill issue. When I called Thor assuming they would send me a new grill, they replied that the whistling has not been an issue with 2018 models and that I need to take it in to indentify the source of the noise. Anyone one else with 2018 having same issue. Anyone heard or tried a mesh fix? If so any pictures? Wonder if the mesh would effect engine cooling?
I have a 2018 THOR ACE 29.3 and had the front whistling. Called THOR they acknowledged that it was the front grill and that they would send a replacement. New grill completely solved the problem Don't know why they said the 2018's don't have that problem Mine did, and the new grill fixed it!!!
