We have an old (m reg) vw lt35. We bought it knowing that the suspension needed some work which has just been done so haven't been out and about much yet. I prefer to get one where I can see the work needed cos then you know it's done right, rather than one that has had lots if bits done but by who knows who.
However we chose it over a transit type for our 14.2 pony as the transit ones we saw were just so high up even at he base that the ramp was very very steep and also I wasn't comfortable from a centre of gravity perspective when cornering (we drive slowly and carefully but still). So far we have mainly used the lt35 for collecting hay on hour round trips (btw it takes about 40 ish bales to remain within the weight limit) and it drove fantastically, very smooth and easy drive.
We didn't go for a Renault master type because they are very low slung and FWD which is great for loading but would not cope with our remote very potholed track and the muddy fields we have to park in at events.
I think the lt35 is a little bit bigger too than the transit types usually are, ours has a little area with a bench seat/ locker plus a Luton over the cab. I wouldn't want any more living cos of the weight.
