the mobile.de site has an engligh version... check the bottom of the page.
You have to be very careful with the weights. VRT is based on the unladen weight of the van. This i sthe van from the factory, plus anything bolted on, plus a tank of fuel.
Some manufacturers will quote the van weight as the unladen weight. Some will guote is as the MRO... Mass in Runnin Order. MRO also include gas, water and (I think) 75kg for one person.
It's a bit of a chance but if the van weights over 3000kg then there is NO VRT (well €60 or something).
I was in exactly the same situation as you..4 people but getting a 6 berth. I bought a Knaus Sun Traveler 608k. It is over the weight and has an excellent layout, and is a good quality make.
There are always a few for sale on mobile.de
Another important fact is that as the vans get older (and cheaper) they start to loose things liek 4x full seatbelts in the rear... and headrests in the rear (on the dining areas).
It's easy in Germany to find a fully loaded van. The one I got has upgraded suspension (to 3850kg) air suspension, climate ,reversing camera, awning, roof box. alloy wheels with camping tyres, upgraded interior, upgraded sound system etc etc etc
I definately saved over €10k
The other MAJOR issue is payload.
Most vans are rated to carry 3500kg. Now if you are avoiding VRT then your unladen weigth is going to be 3000kg at a minimum. Add in 100litres of water, gas and 4 people and you have no weight left to carry anything!!!
Solution: get a van that is rated to 3850kg or higher... but then your B licence won't allow you to drive it. It's a tricky one to be honest. If you get a van <3000kg you end up with VRT t0 pay and also perhaps a smaller van that doesn't suit.
In my case I got a van that had already been upgraded to 3850. I got the dealer in Germany to "re-plate" (document) it as 3500. In Germany they are very efficient and when they did this it was noted I could only carry 4 people. Fine.
In Ireland it was recognised as 3500 but 6 people. I might break the 3500kg limit, and I will be breaking some road traffic act, somewhere, but I know the van is safe. I haven't never met anybody who has been fined for breaking the weight although there are random test and some EU countries would be worse than others.
