Am i right in my assumption /hope that when I come to fit heating to my 2003 38 I will find bulkheads with penetrations allready cut out for ducting , or is this wishfull thinking , any advice on doing the job ???, Im plannning on using a mikuni unit . Dont think its as hot as an eberspacher/webasto , but we only want to remove chill . They are highly reccomended by a friend who has used all and says little between them bar price , dont need 7 day timer .
cheers
