...in my corner of the world, überlong buses are a no-no!
The longest you see are Cross-nation 45-ft 2-floor unts with 4 axles - highway only!
A few month ago I saw some "cross-country machines" in Bolivia!!
TRUCK-engine-trans-combo, 2 axles, 2-floor bus, but the lower deck is ALL for luggage and cargo, and the whole bus is LIFTED, like spring-over axle!!
Leaning like crazy on the highway at speed, but going the "normal" country roads they need the added ground clearance - quite an interesting study!
Hope to get back there again sometime soon, then I will search them out and take a load of pics!
