How fast do you go

The greater the difference between your speed and the normal flow of traffic speed the more likely there is to be an accident. Not necessarily involving the slower/faster vehicle but they are more likely to be the cause of or be involved in an accident. In short: it is just as unsafe to go slow as it is to speed.

I tow at the same speed as the semi trucks. 80 in west TX and 55+ in CA

My fiver tires are rated at 65mph, I ride at 62.

ST tires...62 any state

65 to 70, 68 seems to be the sweet spot for fuel economy.

This is where we try to keep it.

My trailer tires are rated for 65 mph sustained speed so I do not tow faster unless overtaking a slow vehicle. If the speed limit is posted higher, I still do not tow any faster. Many places where I tow have restricted speed for vehicles towing (sometimes down to 55 mph) to which I will adhere. I find towing around 60 mph gives me a respectable speed and fuel economy while towing faster puts additional wind drag into play hurting mileage with little time benefit.

75 if conditions are right and no traffic!

Traveled New Mexico last year on the interstate the speed limit was 75 for trucks. I have never seen so much carnage on the side of the road. Big rig after big rig piled up ether on the left side of the highway or middle of the highway. On the good side out of all that bent metal I didn't see one RV tore up... Of course I guess they could have been under the big rigs LOL. I travel 55 to 60. 65 in New Mexico out of necessity. Here in the Great North west speed limit is 55 it's a rarity to see a big rig tipped over.

62-64.

when towing on 2 lane, usually around 55-60 and pull over for traffic behind me.
on multilane around 60, but if there is much traffic, I'll get in the right lane behind some trucks and keep at the speed they are going at. Keeps the trucks from needing to pass me if I am going slower, and me constantly pulling out to pass if they are going slower.

62
