The difference between a T30 & T32 is 2 tons. The T30 is a 3 ton Van and the T32 3.2 ton least that is what I was told. You have one 11 yeaar old lad who no doubt can help you out at the campsite. I have seen many young ladies at Foorest Fields on their own with a child. The last one had a young baby in her arms and managed to get a motordome up on her Kombi. I have seen a few women drive in with Kombis that were converted so it seems to be the van of choice. Not sure a panel van is the way to go as they get hot inside unless your conerter is putting in windows for you. I'd rather have a manual that auto as I feel iyt is more to go wrong. Might be worth looking a few vans in a Dealer and see what you get , it should help you make up your mind a bit more or have a look at our photo gallery and see the different ones on there.
Small correction, difference is 200kg, not 2 tons! Might be small, but 200kg is very useful in campers...
