1. Zetros 2733 A 6WD
The Zetros is another all-wheel-drive beast on the list and a 6WD, for that matter. The 2733 A is based on an Actros platform. Some Unimog DNA is also involved, helping it offer amazing traction due to its proven mechanics and 6WD system. It has highly customizable living quarters. The weight of this six-wheeler ranges from 25 to 27 tons, which is a formidable number.

The Zetros 273A 6WD is a machine with a 7.2l inline 6-cylinder engine. It has approximately 1,000 feet per pound of torque at a low RPM, somewhere between 1,200 and 1,600. With those torque figures in mind, it’s clear the Zetros 2733 A 6WD can go anywhere (via Pktrucks). The interior of this RV is utilitarian to the max, which is expected because this is a car for hardcore outdoor use.
