appropriate expressway speed?

Trailer tires are speed rated for no more than 65 MPH. Faster than that and they start to deteriorate.

between the posted minimum speed limit and the maximum speed limit whereever I am most comfortable at with the traffic around me. Setting myself to say never over 60 will probably get me run off the road through most of SC, GA, FL and who knows what other states.

More than likely with a TT your limiting factor will be your trailers tires. You have to remember that ST tires are speed rated.

Most RV tires are classified as ST trailer tires, rated for 65mph. Depending on temperature, I am comfortable running 65-72mph.

Having pulled in all states we found just running with the trucks was the best. What ever speed they are running just fall in line with them. Makes life a bit more relaxing. California law is 55mph but most trucks run 62. If you fall in line the troopers will not single you out of a line..

I agree. I used to drive 68 to 70, but then you are passing the big trucks, in & out of passing lane, very stressful. Driving the same speed as the trucks makes for a more pleasant driving experience.

I keep it around 58 through all three of those states and NC all the time.

I run the posted speed limit up to a max of 70 towing a 5er.

Right lane 60 to 65. It works for me so far and i plan my trip time accordingly.

I drive the posted limit.

What works for you? I have no idea?

I get my best mpg around 60 mph. The trailer tires are rated at 65 mph. Sit back in the right lane, light a cigar, grab my cup of coffee and watch the scenery roll by.

Works in the big truck too as it's governed at 63 mph. That's why so many trucks run 62ish as that's where their governor's are set. Canadian (Law 100 km/hr or 62.5 mph) and U.S. fleet trucks are in the 63-66 mph neighborhood for insurance purposes. They get better mpg if they open the engine up but insurance costs win.
