I don't think a picture will help much (and I dont have one to hand). It's a coachbuilt motorhome (burstner 6200) so just the fiat cab and chassis remain. I know the model types refered to the load capacity so must have had some influence on suspension etc. Was the length different for different models? Mine is 23ft long (6.2m) if that helps. I am going to call fiat with the vin tomorrow, see if they can help.
