Transit or similar should be easier for a beginner in some respects.
IME modern Transits are supper easy to drive. Drove a mid-'00s Renault Espace once and found it harder to drive than a Transit.
On the vehicle choice, my main question is whether they are going to be mainly static once they get there. If so then a car would be nicer. Something like a diesel passat estate with a roof box would be fine.
Transit or similar should be easier for a beginner in some respects. You are sat higher up and have more road presence than a smaller vehicle.
