top bit of kitt - i had one last year after all that snow - easy fit two inch holes in floor wire up stat and hook up gas , 20 mins top - they sound great bit like a deep v8 , ive got a silencer coming for mine this year .
set stat to temp wanted and it fires up , it hooks up to a 12 volt batt also , i used a spare one just in case it run the main one down . i had mine running 24/7 friday to monday morn last year no problems
you will need to insulate the van tho really or you will be wasting heat - ive just spent 2 days insulating my new one - found a cracking insulatation , 10mm foam carpet underlay , just spray tacked glue to sides and roof with ply over the top .
