Hardware costs for flat-towing (brackets/wiring/tow bar)....

I paid C$4500 for everything Blue Ox (base plate, tow bar, included parts, lighting/wiring, safety cables, umbilical, battery charge circuit, breakaway cable, Patriot II Braking System) profesionally installed by a Winnebago dealer in 2017.
I live in a country where everything is highly taxable, added to the usually higher retail prices. Your prices will be a lot less, I'm sure.
(Towed vehicle not included ;) )

Interesting video Thanks.

AT. Yes. It takes a little practice to line the toad up to the rv.
I will find u a video.

VA-Apraisr 2X. I have the same questions. I hope you don't mind if I add this question. IS an All-Terain better than a standard tow bar?

$2-3k. Its not so much about price vs ease of using.
For me flat towing is easier than using a dolly.
The ramps, tie-downs , trl registration and storage got to be too much work. I find the flat way is the best way.

If you can do the installation yourself. Electrical 12v hookup with a charge line included for the toad battery.
Installing the baseplate.
I use a Brake Buddy 2 which sits on the toads floor and presses the brake pedal. I can use that in any other toad. It uses a wireless signal from rv to toad. Gets its 12v power from a 12v port that you install under the steering wheel.
