You're not going to get much charging through the factory 7 pin plug. The wire from the alternator to the 7 pin plug is too small.
My 02 Dodge Cummins does great no mods except it has the trailer plug in the rear and that's what it's hooked to. I know it's too far but, it does great.
When checking you need to take apart the male part of the 7 pin adapter that's mounted on the camper. The guys building these things get piece rate and so that wire doesn't often get stripped... they just try driving the set screw in tight enough to break thru the wire insulation and that's what I have found twice now. Both times fixing these have had good results.
