Must second everything Greg just said. I had a RV shop mount a similar Unified Tow Brake by US Gear on my previous motor home and previous towed car. Moved to current Vegas and newer roadster that we tow when we upgraded. That was 8 years ago, and it is a snap to connect and disconnect.
It's no big deal to unhook the car, go sightseeing, out to dinner, etc, and hook the car back on. No trailer or dolly or brake box to deal with. Only bad or ugly might be the $$$, but i figure that is just part of the cost of taking a car.
I think we need to stop calling it "working from home" and start calling it "living at work!"
