for a popup.. I would think that maybe run the cables down the outside.... now this would mean that you would need to use a heavy duty connecter on the roof and disconnect the panels before traveling... but with the power cord on the outside you could lower the roof to disconnect and reconnect before you raise it back up...
Running the cable down the inside tho possible appers to have too many problems to make it worth while...
just my $0.02 worth
