I have been thinking alot about switching to a van -
 
 pros
 easier to load the bike (you can use a long ramp)
 bike is out of sight
 bike is dry
 loads of space for gear and tools
 easier to drive than a car + trailer
 
 cons
 insurance
 mpg
 vision at junctions (although you can usually take a different line)
 space to park the van
 
 The pictures I have seen with bikes loaded into people carriers look very cramped, but I have not seen one in the flesh.
 
 I guess it comes down to how many trackdays and trip for servicing that you do, compared with normal car type trips
