I read a couple comments under the video. My favorite:

"Sweet! Now I can finally haul my 40' fifth wheel with my Chevy Cavalier! I just need a hitch, then a 1-1/4" to 2" adapter and then the tow all and I'll be set! I'm just kidding everyone, obviously I would use a Geo Metro as the tow vehicle. You know, better MPG and all..." Backwoods223

As a person who is licensed to pull double/triples, this concept scares the ---- out of me. One more wiggle point, hooked to a vehicle that is too small to handle the weight, driven by someone that is trying to cut corners....just buy the correct truck.

It's actually =less= "wiggle point" than your doubles dolly, as the Tow All Dolly is attached to the TV's frame via the receiver hitch and chains, so there's no wiggle there, whereas your doubles dolly is attached via a pintle hitch and allows for 2 points of "wiggle". Given that a proper towing setup means that the TV stops itself and the trailer stops =itself=, you've now got 2 more brakes for the whole thing, making stopping safer. Given that the same basic engines and transmissions are used in 3/4 to 2 ton trucks, how is the hill-handling power any different? You are, or should be, still constrained by your GCVW anyway. As for length, these dollies actually allow the FW to turn =shorter= than a TT, because the hitch point swings to the outside of the turn, pulling the FW with it.

So my question is now that the hitch point is moved several FEET back of the rear axles of the TV, how does it react in a high speed evasive maneuver??
I know there is an axle directly under the hitch point, BUT the wheels are designed to swivel, so as not to drag when the TV turns.
It would interesting to know how it would deal with that type of situation.

So, how do dump trucks and cement trucks, with tag axles, handle in an evasive maneuver?

Personally, I think they're an interesting idea for people who might want to use an SUV to tow a FW or someone who wants to tow a FW an not lose their pickup bed.

Well tag axles on dump trucks and cement mixers, only provide additional support, they don't have the load centered over them.

With this device the point at which the 5er acts on the TV is now several feet back of fixed wheels of the TV rear axle.
The wheels on the dolly are self steering. Going straight down the road not an road not an issue, but when the TV turns this extension to the frame will swing out, and not the 5er is starting to push it sideways, which could result in an over-steer condition in the TV.
