welcome to the shop blue
the set is: factory installed deluxe model, factory installed standard, and dealer installed 'basic', which seems to be the most common

you'll find pics of 3 different styles of TF heaters here - there's a 4th less common style I haven't got pics of up yet - eventually there'll be a 'tech tip' on the TF heaters .... when life allows time grin
