I asked my boss last year that a small truck would be useful, fit it out with a small Hiab or similar...he frowned at the idea
too hard to park, cost more in rego, shit resale as the market is much smaller for a LT, and utes are much easier to get a hold of spares and repairs
Vans are shit...noisy rattly tin cans, it is great to have more space, but this just becomes a burden as you tend to fill it up with shit you don't need just to use the left over room.
I have seen so many tradies that run vans, and if those were also classed as work sites, the unions would shut that shit down pronto, some cnut's gonna get killed in there!
