What to do first??

My aim is to get windows fitted all the way round.  Four on the sides and two on the back doors.  I'm going to go for 'Privacy' glass which should hopefully look cool on a white van.  Then I'm going to source a nice Rock 'n' Roll bed and insulate and line the insides in a medium grey carpet.  The flooring will probably be some sort of laminate or linoleum.  I haven't decided yet.
