In 2015 when we were looking to order a Tiffin Allegro Bus to fulltime in, we spent time reading comments on the Tiffin Owners forum. The electrically heated tile floors were highly recommended, so we we added them to our order and are extremely glad we did! Often just having the floors on a low setting will keep the coach comfortable when it is not very cold out. It is very nice to get up at night to use the bathroom and the tile is comfortably warm. The biggest issue with electrically heated floors is the need for 120VAC.
