I have a 2024 2660 BS. It has the on-demand hot water heater which works great. I have it plugged into shore power but oh plumbing system has been winterized. Two different times now The blower on the exhaust of the hot water heater is blowing out air. The hot water thermostat is in the off position and the gas is off. just the a blower is randomly running. Has anybody had this issue or know what causes it?

If you're winterized you must turn off the switch outside under the units panel. It is slightly to the left, you can't miss it. This is the master off switch.
 
Happened to me early last month. Took the Brinkley in for warranty work and a Furrion tankless water heater replacement (worked during the PDI but not on the shakedown trip!) plus winterization. Brought it home to storage late afternoon. Went to lot next day to remove batteries and cover tires. While doing so the Furrion heater's exhaust fan turned on with no propane on. Dealer forgot to turn switch off at the heater so switched off and fan stopped. It was about 38 degrees outside and I believe the heater's anti-freeze function was trying to do its job. Gave me the opportunity to loosen the drain valve and assure there was pink anti-freeze in the heater itself. That was a relief!
 
On which brand WH?
I answered in accordance to the OP's unit, which comes with a Furrion tankless system.

To add, the switch is seen here. It's white on the left right under the fuse.
