It looked interesting to me until I saw the oil pump belt replacement at 150k. Have to pull transfer case and trans to get at it since it's in the back of the engine. Just my thoughts, otherwise I liked the idea.
Pulling cases and transmissions are not very difficult. YOu do need the equipment such as lifts, supports, and jacks that make the job easy. You can have a transmission out of a 1/2 ton truck in 3 to 4 hours and if you servicing a high mileage truck, time to change out the rear seal at the time. No point fixing the truck, and still having an oil leak....
