Waaaaay too much science for this country boy.
What I do have is experience watching those pop ups from behind the wheel of my rig.
1) most of the pop ups I have seen have small tires. They tend to hop around at high speed.
I saw one break loose from the tow vehicle. It hit the car passing, the car behind and disintegrated across the median. All told 5 vehicles were involved. 3 people were taken to the hospital.
Another time a pop up hopped so bad the tow vehicles rear tires broke traction. Both tow vehicle and pop up met a Jersey barrier. The barrier won hands down.
2) Passing can be an adventure of a lifetime. Pull out or into a lane to quickly and the trailer starts to sway, which can become hopping very quickly.
Lane changes and turns need to be very smooth. Like silk.
3) Road construction is the enemy of every pop up produced.
Uneven lanes and road debris from construction can ruin your day quickly. Be aware and slow down.
4) Most trailers and pop ups have speed ratings on axle and wheels/tires. These ratings are our friends put there by very smart people who *have* done the science.
In addition to the wrecks I have witnessed, I don’t have enough fingers and toes to count the number of times I have seen Law Enforcement pull over vehicles because the trailer it was towing was just this side of a wreck.
I plan on buying a pop up to do some traveling in soon.
I don’t plan to drive over 60 mph so I will probably stick to the more scenic US and state routes.
Good luck on your 90 mph trip. Let us know how it works out.
Eh, not planning on going any more than 65 mph. The 90 mph assumed doing 60 mph and a headwind gust of 30 mph.
Otherwise, yes, that’s all good advice. I’m almost the antithesis of the guy who roared around me on a Texas 2-lane highway with the biggest flatbed trailer I’ve ever seen behind a pickup — at about 85 mph. (I was doing ~65 in a minivan [and no trailer] at the time.)
