I personally think with the way you are currently camping, you are better of towing a caravan or moving to a larger Crafter
If you can't fit everything in a current T6 and sleep in it, then a newer T6 isn't going to be better.
Cheaper and nicer to have a decent Caravan and tow it with your current work van, if you are staying places longer than a night.
Campervans are great for those who are willing to sacrifice space and comforts for the ability to be be traveling most days, but if you don't do this, then in my view its not worth it.
Edit: Campers are cool, but as you already have a T6, you already have that
, you just need more space
This second van needs to be a daily driver ,80% of the time, and a camper 20% of the time.
That means shopping, underground carparks, school runs, vet runs, driving uptown and to the family... Cinema, seaside, etc etc.
So a crafter or man etc is not an option for us at this stage as the are too big and tall.
We also have a short length drive with lean-to at home, so again a crafter would be too large to keep at the house. (Remember it's a daily driver,)
A crafter and larger van is not good as a daily driver on fuel, especially a converted one..... We're looking ,20% camper use..... So school and work run most of the time.
++++++++
If this project was for a 100% camper, then I'd agree totally with you ....
A T6 is to small for a long term camper, even a LWB.... A caravan or crafter/ motorhome makes perfect sense, and is the obvious way forward.
But at this stage we are 20% camper, 80% dad's taxi.
So at this stage were thinking kombi camper should suit....
However the secondary problem is transporting all the additional kit we take to events.
Ie disc-tent, speakers, lights, flag poles, etc etc.
