I would stick to cuotas in northern Mexico and libres south of Vera Cruz. The cuotas in Yucatan are really expensive and the libres are excellent. There are no cuotas to the archaeological sites - but the topes can be awe-inspiring across Yucatan on 186 and "amusing" on 307 just south of Tulum. Wrecked rig in March just west of Orizaba on 150D. "Mexico Mike" wrote us to never use that road after mid-morning since the catabatic winds from the coast will hit the cold air coming down from the glaciers on Pico Orizaba (18,500') and you wind up with almost 0 visibility fogs. This is a great 4-lane divided highway otherwise. The Pemex in Orizaba is a great over-night spot. The attendants have been extremely helpful and the truckers have been as friendly as one could hope for.
