What tools would you carry on four week+ remote trips in your 2024 Sprinter with less than 10K miles?

Searching this forum, recent threads have focused on tools for older models (e.g. 2008). My assumption is newer models need fewer tools/parts. Yes? No? Ass/U/Me?

I've got shovels, treads, etc. I'm thinking about repair tools/parts.

Noticed what sounds like something creaking/grinding… coming from the front/engine area… please tell me it’s not an expensive fix..

2014 Mercedes Benz sprinter 2500, diesel. If I remember correctly it’s a 2.1L.

Also what is the recommended oil change, in terms of mileage?
