Most Texas tolls are in the city where there are plenty of other options. Only problem is that Navigo puts you on the toll roads for some odd reason. In Florida, it won't even recognized the Orlando toll road as a road (but trust me, it's 12 dollars well spent ).
there was a time last winter i was going from Lawton OK to Milwaukee. Got to OKC and had a choice of either running 44 to 55 through a winter storm or 35 to 80 for an additional 50 miles with no weather at all. Took the 35 route and sni paid the tolls on it. Only time I ever drove that much through kansas as company.
