Oh no thank you very much, seen way to many Bremach stranded with owners waiting for parts to be shipped. This is a cool looking vehicle with many good features, but I wouldn't not want to take that out of Europe. After all it is an Italian brand with almost no dealer/parts network.
You should, if you care about reliability and the ease of getting service/part abroad. Unless you just drive around Europe.
When you say a major marketing brand means a good support and quality this would not be true. This is the reason why marketing departments spend millions of dollar to build a brand. I know what I am talking about, as I am one of these, though in a different segment.
Actually you don't need to deal with Bremach very much: engine comes from Iveco, tranny is Allison, at least for Germany, Austria, Swiss you can deal with a German importer, who's known for a great support, up to 7 days per week.
The dealer issue is as worse as for all US companies. I can't get a simple thing like an oil filter here for my 7.3 idi, at least without translating the technical data from motor craft into similar data from an European filter brand, like k and n, MANN... by myself of course. Getting an alternator was almost impossible. Ring/ pinion was impossible, so I ordered from summit and received these after 8 days! Though it cost 130$ shipping.
Back to the point:
All parts for the all wheel conversion and the third axle are parts of the company who made a conversion for how many trucks like this? I don't think you can get any parts from them in 10 years...
