Id Expensive Mexico Toll Roads!

I went into the site but there is nothing for a Motorhome pulling a car (toad).

As near as I can tell we are almost always (but not exactly) charged as a two axle bus pulling a car - you have to first do the calculation for a bus and then do a separate calculation for a car and then add them together. But sometimes we are charged as a 4 axle truck. I know people often say they have been charged for having dual wheels on their axles but this has never happened to us. We are a motorhome that looks like a bus so to them we are a bus. Perhaps they see different motorhomes as being something else? Since many of the toll roads are private and owned by different companies and each toll collector sees through different eyes it is difficult to know exactly how much you will be charged at each toll. In our experience if your RV looks like a bus they will charge you as though you are a bus - if you tow a car they will charge the additional toll for the car - and add them together for a total - they usually give us two receipts - one for the bus and one for the car. That has almost always been our experience - your experience may vary.
