My new '73 Open Road/Chevy C30 Chassis--How to learn?

Hi. I have a 73 Superior Coach on a Chevy 30 van. We have had it for 11 years and have been to all 48 lower states. We would be in Alaska now except for a minor health issue for my wife. The van is a Chevy with lots of parts available. As for other stuff, search the information out. Know the brand and model number. Or ask questions for specific instructions.
Last summer I transplanted a 91 motor and transmission into mine.
