Hmm, interesting that those insisting on extra margin with a tow vehicle are less interested in the extra safety provided via driving at what is, in California at least, the posted speed limit for vehicles pulling trailers.
Here’s a little math exercise: rate * time = distance
Driving 4 hours at 70 = 280 miles
So say your show is 280 miles away, you save approximately 1 hour, 280/55 = 5.09, if you drive at 55 instead of 70. 1 hour and 1 minute if you want to be picky.
If you drive 280 miles at 65, it will take you about 4 hours and 20 minutes, so you’ll save 40 minutes over driving at 55.
Great line from the song I Feel Lucky; the stars might lie but the numbers never do.
I’ll put my trust in the engineering specifications of my vehicle which includes wheel base measurement, transmission, etc.
Either way, it’s all about risk tolerance and management.[/QUOTE]
Since this was directed at me and my 4 hour minimum hauls, the speed limit here is currently 75 mph. It is going up to 80mph tomorrow (asinine imo, but whatever). If you go 55 you will cause an accident when someone on their cell phone rear-ends you. I’m being serious, not flip, it is dangerous to go that far under the speed limit on the interstate here.
There are no posted signs about trailers going 55 here, I have never seen those anywhere I haul.
Also, if you read my post, I said interstate speed (FYI, I actually only drive 70 mph assuming good road conditions/weather) when using a “truck.” The truck I’m referring to last hauling to a show with is a 3/4 ton diesel pulling a two-horse featherlite. You don’t even have a clue the trailer is back there with that truck.
My Expedition experiences are on highways, because I don’t want to die going 55 on the interstate when someone rear-ends me, because that IS what I drive with the Expedition towing. Also why I was only going 40 when the horse started acting up.
So apples and oranges.
