Do I have this correct... Max speed limit is 65 mph when towing any trailer and 60 mph if the trailer is over 10,000lbs?

Yes, max speed limit towing is 65. Whether that is enforced or not, well...

I think Washington requires trailer brakes on anything over 1500 pounds. Not sure if they would consider flat towing a car as a trailer, or if they would just say anything towed weighing over 1500 requires brakes regardless of what it is. Any I have heard that any time a vehicle is towing anything, the "truck" speed limit applies, which is normally 60 on the interstate.

The information posted for WA says trailer brakes required for weights over 3000lbs or 40% of tow vehicle. Max speed for pulling trailers is 65mph.

That also applies for flat towing. I had to install a braking system on my mom's Ford Edge so she could legally tow it behind her motorhome.

That's what the RV places say. If it's that heavy what's the difference between being on a trailer or flat towed. Puts the same amount of stress on the tow vehicles braking system.

No supplimental brakes required for flat towing in Wa State. A towed vehicle is not a trailer. RV and brake dealers will tell you otherwise.

still no thoughts on double towing?

While in Montana, we saw several folks pulling either a fith wheel or regular travel trailer with a boat or small tailer in tow. It looked pretty scary as they snaked their way down the interstate at nearly 80mph. They definitely used their whole lane. I imagine they could not back those outfits up very well.

1) I have never seen a trailer that was setup with what I would consider a proper hitch or tow wiring to safely pull another trailer. A second trailer would have to be either light enough not to need brakes, or have surge brakes on it.

2) Haven't checked the laws myself, but I was told in Washington, you can only double-trailer if you have a CDL.

My motor home manual reccomends a trailer brake for towing anything over 1000 lbs. it's just a recommendation and my motor home is small.

Not sure about WA but in IL you could double tow no CDL but the first towed trailer had to be a gooseneck or 5th wheel with a class IV receiver hitch at the back to tow a second trailer.

If you ever wondered why some 5th wheel trailers have hitches on the back from the factory that's why. Not exceeding your truck's GVWR could be a challenge though
