There are no "Speed Limits" in Texas.

As to the question about trailers, I *THINK* they changed the law recently to clarify that the lower speed limits was for 'heavy trailers'.

Drive it like you stole it!

She comes in at 8,500lbs roughly. We run 65ish behind the cummins maybe 70 depending on how far the trip is.

I always run about 65, but new trailer tires are a lot different today. I will tell you most people that tow just do speed limit and not worry about it. My uncle always bought crappy used tires and they looked like they blow just sitting there,much less at 70. Just chalk my experiences to bad child hood memories. I still wait for tire to blow out on each of my trips.

The faster you drive the less reaction time you have when something goes wrong.

I drive at or slightly over the speed limit on the open freeways. In town I drive with the traffic. The speed difference comes in with the longer you have to drive. From my house to Falcon is 485 miles. If I drive at 65mph it would take 7.4 hrs. (all other issues factored out). If I drive at 75mph it would take 6.4 hrs. That one hr. doesn't sound like much, but if I leave here at 5pm it means the difference of getting there by midnight or 1am. And anyone who has made these long drives will them you after 10pm every hour you drive is like 1-1/2 hrs. and you progressively get more tired and weary. I don't advocate driving excessively, but do believe in maximizing my speed in the open highway
