Been there and to be honest I have no regrets going down the Toyota route for many reasons.
Mainly that you are paying for a badge in as much as the reliability is the same if not better on the Toyota.
You get alot more toys as standard on the Toyota (AC, electric windows etc etc).
The LWB is like a tardis inside and makes a superb camper conversion, me and my partner have plenty of room and with a 3way fridge, hob/grill and other bits we are very happy over the last van we had which was a T4.
I use the van to work and back every day and it's a dream to drive....no question, my partner whom is a nervous driver enjoys driving the van as it is so easy, plenty of grunt from the 2.8 (not the crap 2.4's on the T4) and the Auto box shifts fine.
Ask anyone here.....youwill have no regrets
