Factory heated stuff

[djlcanuck]

I am a BB wan'a'be and have been reading every ad I can find until I
get the right bird for us. I recently saw an ad on Ebay that says
Heated tanks, Heater under the sink, heat tape on all pipes. All this
is very importtant to us cold Canadians. Can some one tell me if these
options are standard on all BB or if this guy has gone out of his way
to do some serious winter camping? Are all BB plumbed with copper? Has
anyone had problems with leaks? I have an Allegro that was plumbed with
copper and had a lot of leaks until it redid it all with flexplex.
