Haze with furnace running

[Jeff51]

Hello. I own a 2016 Tiffin Allegro 31SA, purchased new one year ago through General RV. This fall during our first cool weather camping, we noticed a haze in the air in the main salon area while the furnace was running. The dealer has replaced the furnace under warranty, having found a CO leak in the original furnace. We still have the smoke or haze. It does not have hot or burning odor and neither onboard or aftermarket CO or propane alarms are being triggered. We’re well past the typical burn off phase of residual lubricants in a new furnace.
Service dept. now states Tiffin is aware of problem and tells them that the factory installed furnace supposedly runs too hot for the type of ductwork they utilize. Their suggested fix is to ship the dealer a different “limit switch” so the furnace air doesn’t run so hot, causing the haze. Ready to yank my remaining hair out! Has anyone heard of or experienced anything similar on their newer Allegro coach? Any feedback greatly appreciated!
