I purchased a used 2006 Grandby about a year ago, have done various updates and minor maintenance, and now would like to install solar.
The camper appears to be pre-wired based on this thread (two set of wires going up to the roof and build date is 2006):
So there are wires, but there is no feedthrough/plug through the roof panel or any visual way to see where one could cut through the roof to access the wire ends.
I contacted 4WC with the build and delivery information (e.g. build date, original purchaser, serial number), but their customer service said that they are unable to find the records or documentation for this build.
I haven't seen any pictures of someone using these wires on Grandby, and reading these forums it sounds like there is some variability in wire placement, particularly on the first year after pre-wiring started.
Does anyone have suggestions on how to find the wires (without making cuts in the roof or headliner), or has anyone found the wires on a Grandby from this year?
