The VW vans are more popular here as well. You can find some Hi-ace camper conversions, but not so much as VW vans. There were actually Japanese companies delivering new Hiaces (Super Custom) with camper built in, in the nineties.
But since we are next to Germany, the VW vans have always been here. Thats okay, they are part of the car history, but I don't like them.
First of all, when you want to do some offroading, you want to have the VW T3 syncro because the others are not suitable for any serious offroad. The problem with the T3 is that the diesel engines are so tiny. They have cooling problems all the time, when going up the mountain (on the highway). It's only a 1.6 diesel engine, I mean common... My Hiace has a 2.4 liter engine, and it's the smallest there was available.
And the T3 only has one low gear, while on the Hiace you have all the low-gears just like Hilux and LC etc.
There is only the 2.1 liter petrol engine that would be an option, the other engines are just to small.
But yes, I have a 2.4 liter diesel engine. The Toyota 2L engine that can be found in a Hilux as well. It's not fast, but it's fine. It allows me to drive on the highway at 100km/h (faster is possible, up to 120km/h, but not so nice).
And it gets going through the sand just fine with the little amount of horsepower.
The high-top is very rare. I mean it's original Toyota, I didn't even know it existed. That and the fact that it had only like 100.000 miles on it, meant it was a good buy. The bottom was still hard too. But the edges are crumbling a bit. This is going to be fixed this winter, I even found new panels which can be welded in, so nothing has to be fabricated.
