If one was to buy a new German Motorhome which will be used for touring Europe, but when not doing that will spend longish periods at addresses in the U.K.and Portugal where would be the best place to register it ? In theory it could have English, German or Portuguese registration plates, we know the Portuguese are pretty hot on foreign registered vehicles overstaying the allowed six months, but to base it there is expensive, does the the same problem occur here with foreign registered vehicles? Any ideas or first hand knowledge would be appreciated.
