As a retired RV transporter I will agree to some of the other haulers statements. Those of us with experience know that driving fast cost more in fuel. Thus, we keep the speed down. Also, most transporters are either their own transport company and either use a dealer tag or a transport plate, or work for a shipping company. I've done both. Thus, taking a pix of the plate will get you no where in most cases.
In ten years of hauling, I can't ever recall having a blowout on a new rig, though I have on my own rigs and I've owned about twenty five over the years.
Third, most of us carry a CDL, you get many tickets doing that your insurance goes up and you chance losing your license. That means, NO work for a long time.
Granted, there are those who do speed or miss-treat a new unit. But mainly they are new guys.
