Repave driveway, drainage, costs?

I think, without any pictures at all, the thing remains a bit low-calorie ...

so here are a few calories for the evening:
In the bottom photo, the front part is the driveway ('sidewalk'), which ends on the left (hedge)...

Oh, who even sees a serious need here?
Apparently, the substructure of the pavement has settled under the right lane of the vehicle. If there is no accuracy prize to be won, three (double) rows of stones need to be lifted and relaid after filling up. Apart from the fact that it might rattle a bit at the gutter when driving over it, there is really nothing (?).
Does thread 46017 with the crossing for the motorhome parking space "belong" here?

well, the entire condition is not shown, there is already quite a bit "not flat":



yes, the motorhome driveway is on the other side of the house.

And the drainage in front of the garage is not particularly easy to see in the photos, I have a better photo taken "from the inside":

As it looks, your pavement will last a long time but no longer looks good. If it is worth it to you, have it redone. Remove everything, including the sub-base (about 30-50cm), put in recycling, compact it, add gravel and new paving on top. Have it made for a load of 10t, because of maneuvering the motorhome and the craftsman's van.

Honestly, I can think of 100 things, if not several hundred, that I would do first.
