Recommended PDI we should do before accepting unit?

[DHart]

We are edging VERY close to closing the deal on a new 2020 36RSSB3. May close a deal in the first week of January.

If you can recommend things we should be sure to check before accepting delivery, please advise.

Of course we will do a good bit of camping in the rig, close by, with plenty of time for fixing un-noticed issues, before we head out on the road for longer trips.

Thanks so much!
