In Texas, we have commercial truck speed limits that are 5 mph lower than light duty trucks and cars. Many areas will have a night time limit of 65mph for all vehicles. No minimum for towing. Posted speeds have been increased to 75- and 80 in some places in west Texas. I towed my 3124KB to Arizona recently and on the first full day, I was running close to 70-73mph. Fuel mileage was almost down to 11mpg. I slowed way down to 60-62mph and increased to 14mpg. That was total weight of close to 9k with Tundra, cruiser motorcycle and loaded TM.
