Are you sure?

16. Connect to air source or RV to test towed vehicle brake application. Apply air and watch towed vehicle brake pedal depress. Vacuum pump will cycle after each brake application.

It looks like v2.0 also requires a DP's air brakes but works more like other systems and does not require separating the master cylinder from the brake booster.

Their towed vehicle compatibility chart lists which M&G system is required for which car. My 2020 Equinox requires the v2.0 system. The 2018 and later Jeep Wrangler JL's also require the v2.0 system.

But I've never used the M&G system so I'm not positive.

I've had an M&G System on all of our toads; first with a gas model without air brakes, and then on a diesel pusher with air brakes. They are great to work with and the hook up is easy. just connect the air line.

I got an invisible brake on one toad and Airfoce on the other.
Both work well for me.

M&G Car Braking System for coaches with HYDRAULIC BRAKES
For motor coaches with this type braking system, an air cylinder is mounted between the master cylinder and vacuum booster on the towed vehicle. A 12-volt air compressor, an air accumulator tank and a proportioning valve are mounted in the coach. These units are in the power pack, and are mounted externally on the frame of the coach. One air line connects the motor coach and the towed vehicle using a quick disconnect.

Interesting. I wonder how they control the braking effort. Do they tap into the motorhome's hydraulic brakes so they can sense how high the hydraulic pressure is? If so, that would give me some pause.

Yup.
That's one reason I don't want to use that type of system. Sure, if properly installed there probably won't be any issues. But, it adds one more point of failure to your coach's braking system.

I’ve had 2 version 1’s and neither required drilling any holes in my CR-Vs.

Rvi3 brake for us! Works great. Get the battery charger and direct line 12 volt to brake they sell for toad also! So easy and the smallest. We use it in our Honda Fit and love it.

Switched to M& G engineering brake system. You may need help for initial installation, but after that easy setup. Works off of your coach’s air/brake system,. Have had it for last 5 years , very happy with it

We have a BB on a CR-V and the brakes are not overheating in the slightest.

I use the Invisi brake system. Works well. Stays installed all the time. Main box mounts under drivers seat (tj jeep) completely out of the way. NO WHERE NEAR the 1500 to 2000 bucks you said you had in the other unit. It took me 2 hours to install this unit myself, with my Grandson helping. Just my 2 cents worth. MOMCAT

Not sure what system you are referring to, but I spent a total of $820, including the breakaway cylinder, for my M&G Engineering system. Like you, mine is self installed.

I am referring to post #1. Also...I am not knocking anyone elses unit. AGAIN... I just tried to answer the # 1 post. I read from the front to back. MOMCAT

does a four down towing need a braking system

Just as much as a trailer or car/dolly combo needs them, yes.

If by need, you mean required by law it depends. In at least some states, motorized vehicles are not considered trailers and thus are not required to have braking irrespective of weight.
In most states there are weight limits on trailers for whether or not brakes are required by law.
If by need, you mean want. Want is subjective.
The laws of physics always apply. The heavier your loaded rv plus toad, the longer your stopping distance. The faster you drive the longer your stopping distance. The slower your response time the longer your stopping distance.
I also think the relative weight differential of your rv to toad matters in decision making.
My observations over 20 years of rving is that in practice there are a fair number that pull toads that have no toad brakes. Skewed to lighter weight toads for the reasons I mentioned above.
