I’ve started learning German language and immediately found this travel blog. It still fits ExtremeRVTravel theme so couldn’t resist posting it.
Unimog is well known Mercedes (Daimler) 4×4 truck used for firefighters, utility trucks and many other purposes. Due to its reliability there are quite a few trucks converted to RV, although not as many due to high price.
Feel free to check their pictures on the website, which could be translated by Google.
