The Wanderlodge Owners Group board has just about any info on the Kohlers that you would need including all manuals and parts lists, trouble shooting and complete rebuild with pics if needed. I have had two Kohlers and here are a few things I found out the expensive way.
The Perkins 4.108 engine will run longer than you will ever need it providing it is maintained; the generator head, not so much. Early Kohler generators bought the heads from the cheapest supplier. That lead to there being multiple changes even in the same model year, sometimes in the same model week! Known failures are rear bearing (resulting in stater and armature damage), voltage regulator ($350) diode array ($300+) control box wiring/components ($??) etc. The rule of thumb is if you have to spend more than $500 total, replace the head, Central Georgia Generator is our friend. About $1300 for a new tech brush less head. Bolts right up. Clean reliable power probably for as long as you own the coach.
One more cautionary tail. One guy on WOGGERS board is a stickler for ALL ORIGINAL on his 1985 model coach. He has both the skills and the facility to do things right. He spent $4000 ( not including his labor) before he gave up and installed a new head.
YRMV Good Luck!
