Here are some converter locations.
2011 Great West Van Legend converter in upper cabinet behind that round vent. To get to it you have to remove the fuse box just to the left.
2005 Pleasure-way Plateau with the converter under the ottoman seat. You have to remove the cushion and a plywood screwed in panel to get to it. Note this was a non-intelligent PD 9200 converter but had a plug in for a PD Charge Wizard I bought later. It was easy to do and I was able to mount the module interface inside that battery disconnect cabinet just outside the ottoman. The newer PD 9250 intelligent converters don't have a module readout. There is not much to do other than to look at it out of curiosity.
