I'm not sure where all this concern about tow bar compression comes from. There are many RV'ers that tow a toad with no auxiliary brake system, resulting in a perhaps 3,000 lb or so push against the tow bar every time the motorhome stops. I don't think a backup attempt on reasonably level ground would exert anywhere near as much force.
Now you startin that logical thinking,......and you know that don't fly here !

Think of it like this....There are a lot of pivot points and things to consider when using a tow bar to tow a dinghy. There is the connection to the MH hitch, the wheels of the motorhome, the overhange length, the connection at the toad, the front wheels of the toad, etc. It is like trying to push a piece of string. Who knows how twisted it will end up. If you pull the string, everything stays nice and tight and in a straight line. When you push and have several pivot areas, things get binded up and could bend and/or break. I spent too much money on the toad, tow bar, brackets, MH to chance breaking something. If your toad has enough power (and frame strength), then pulling backwards (with MH help) could work. It is still pulling the string in a nice and tight straight line.

It's really easy to back up a toad. You disconnect it, which takes about 2 minutes, you back it up to wherever you want it to be, you reconnect it , which takes about 2 minutes, and away you go, without worry of bending tow bars or scrubbing tires, or inciting debates on this forum. I've had to do it exactly twice in 10 years of towing 4 down.
And just where are you going to find this perfect piece of ground???
I've backed up enough trailers, including double trailers, in my lifetime to know it does not take much to throw them off track. And I'm reasonably sure that the same applies toward a toad connected by towbar.
Wouldn't a toad w/ the steering wheel locked on center.....become kinda like a 2 wheel trailer ?
No, it would become a 2 axle trailer with a spread between the axles. But not like a farm trailer because the steering is of different engineering.
And don't forget that many of the RV style tow bars are "tubular" with a sliding rod in them.
Most if not all vehicles have the front steering systems set with camber, caster and tow in, set so that the vehicle tracks dead straight, going forward, not in reverse, watch the secret service do an evasive turn arround in reverse and you will see how fast the front tires turn into the wheel well. With the addvent of power steering, the effort to turn the wheel became less.
I drove several vehicles that did not have power steering, and if I tried to do a reverse turn pertty fast, I could feel the steering trying to go to the stop of the turn.
That said, if I have time I will detoad, but thaks to all I learnt something valuable.
If we need to back up with toad attached, I will start the toad, place it in recerse and have my wife drive the RV and coordinate the reversing of the RV, engine runing and in reverse slow.
I do not belive that the tow bar will be damaged. It will be a coordinated pull-push, I also try to not get into situations that require me to reverse or make very tight turns.
If I am not shure of where I'm going, I will stop and walk to see where I have to go, and if I can get out. Specially in parking lots of retaurants and stores.

We've tried it in tight situation with two vehicles. A few inches or a foot was all we could do. Even with one of us behind the wheel trying to keep the tires pointed right.
Someone might be able to do it but we couldn't. It turned tires to lock and scooted them. Not a good thing for them or the tow bar and mounting plate, frame etc.
