We just did the walk thru / PDI on our first motorhome. We found some interior cosmetic issues, repaired that afternoon by a local vendor, and a couple missing / broken items that were in most cases replaced on the spot when possible. For the exterior paint issues our dealer made us an appointment to have the unit touched up by a local body shop.
You need a good checklist to manage your PDI. I have attached the one we used during our PDI. It is a composite of several I found on the web that were "almost" complete. I tried to cover as much as I could by adding sections and moving around sections to cover "every thing".
I doubt I succeeded in that but it is fairly thorough.
In your case you would need to tweek the Mercedes-Benz Sprinter section for your brand of chassis and accessories like leveling jacks.
Take your time and make sure you understand everything before you drive off! I hope this helps...
