For my Washington state friends...
Speed Limit When Pulling Trailers Same As Trucks
Does your summer recreation include pulling a trailer? The Washington State Patrol would like to remind motorists that the maximum speed limit in Washington when pulling a trailer is 60mph. Increased speed also increases the likelihood of the trailer whipping and weaving, causing loss of control.
The weather is nice and the temperatures are rising. This is the time of year that boats, RV trailers and ATV’s get loaded and hitched to the back of vehicles. Driving down the road to have some fun in the sun is a great way to enjoy the weekend. In your travels down the highway, if the speed limit shows a separate speed limit sign for “trucks”, then any vehicle pulling a trailer must comply with that truck speed. So slow down, keep right and arrive safely to enjoy your recreational activities.

WSP Towing TTI tuck in behind a Semi going about 60. Have no problems. I will say my combo likes right at about 65.
I had a blowout 2 years ago, picked up a nail. Just heard it, didn't feel it, looked out the rear view mirror smoke and rubber. Was going 62. I am more cautious now.
