Pretty sure that vin number should read 2PCL33496T not 06T mine is 2PCM33496T1025688 which is only 16 coaches after yours if it is a 96. The PCL vs PCM would tell me it wasnt build as a Motorome Shell. Both speedo and hobbs meters have been changed and Id stick to that story if your trying to sell it. Interior was in deed done by very skilled craftsman. Invertor and batteries appear to be a little on the lite side but with most appliances on LPG it likely does fine.
Good luck on your venture. Get Joe to go through it and you will know what you have and what you need. Hope the Vin info is helpful.
