When I was into bus conversions, there were overlaid diagrams floating around that showed the radius differences between the popular bus chassis'. Didn't know if someone had gotten bored in the past, and made one for these coaches, lol.
The 38 Alpines are on a 1' shorter wheelbase than my old bus was. So I would expect them to turn pretty much the same. The 36 should turn a bit tighter, and 40 wider, obviously. The thought popped into my head late last night, hence the post. Never took more than 40 acres to turn the bus around, so....
