Your now lost heater strip is probably made by the same company that Winnebago used on our Fuse. They are UltraHeat tank heater strips, sold by Annod Industries. The size depends on size of your tank. You can find this info on their website: https://www.annodindustries.com/shop...k-heaters.html
Be sure to also use their recommended glue to fasten the strip to the tank.

Ed I didn't find any recommended glue. They all say peel and stick now.
Yes, I saw that.....I don't think they had peel&stick available on the ones my 2018 Fuse 23A has.... but not sure. A few of my fellow Fuse owners have had those heat strips fall off on the road. Here is a list of glues that UltraHeat recommends for re-installing those strips -- https://www.dropbox.com/s/xxkodolp42..._1901.PNG?dl=0
