So why pick a US School bus to convert to a Motorhome?

On the positive side:-

• They are cheap.  In the US School districts (in Democratic states) have to sell after 10 years.  I paid $6000 for mine (2001 and 95k on the clock)
• They are built like tanks, so a bit of rust is not too much of a problem.  Remember rust is about x10 the volume of the original metal.
• They are well maintained and have a service history
• They are easy to work on, for example loads of space underneath to put tanks
• They are iconic (although the newer short ones based on a minivan are less attractive)

The downsides?

• You are only going to get 10 miles to the gallon - would make touring Europe expensive!
• I didn't know if I would be able to get it past UK regulations - but now you know this is possible
• You will need to import any parts from the US (but parts are easy to find since there are lots of buses in service)
• It costs about £3500 in total to ship it (shipping, insurance, inspection, VAT, paying someone to drive to port).  The actual shipping itself was about £1500
• Headroom is a bit restrictive
• Watch out for rust from buses from Eastern Seaboard - they use salt on the roads
