Very few states have a law requiring an auxiliary braking system on towed passenger vehicles.
I would say over 30 States requiring it is more than " very few " .Towing laws
We love our RVI brake. We used a brake buddy for about 10 years. The RVI is so much smaller and lighter. We were going to get the Air Force, but it's not as easy to change to a different toad.
Since Montana is the state with which I am most familiar, I will use it as an example of the (in)accuracy of towing laws quoted in the reference.
The first thing I notice is that the reference does not state whether the 3000 lb. limit is unladen weight or GVW. In Montana it is GVW, in some other states it is unladen weight.
The second thing worthy of note is that the 3000 lb. limit applies to TRAILERS (as does the requirement for breakaway braking). When we refer to MCA (Montana Code Annotated) 61-1-101 we find that "(82) (a) "Trailer" means a vehicle, with or without motive power, other than a pole trailer, designed for carrying property and for being drawn by a motor vehicle and constructed so that no part of its weight rests on the towing vehicle."! Note that a "trailer" is designed to carry PROPERTY, not people, and to be towed by a motor vehicle. Thus, it follows that a passenger vehicle that has been modified for being towed is not a "trailer".
So, if we want to find the REAL Montana requirement, we must go to:
MCA 61-9-312. Performance ability of brakes. On a dry, hard, approximately level stretch of highway free from loose material, a motor vehicle or combination of vehicles, upon application of the service brake, must be capable of stopping at a speed of 20 miles an hour within the following distances:
(1) 25 feet for passenger motor vehicles, except buses and pioneer vehicles;
(2) 40 feet for buses, trucks, and tractor trucks;
(3) 45 feet for motor vehicles registered or qualified to be registered as pioneer vehicles under 61-3-411(2)(a) when equipped with two-wheel brakes or 25 feet when equipped with four-wheel brakes;
(4) 40 feet for all combinations of vehicles; and
(5) 30 feet for motorcycles, quadricycles, and motor-driven cycles.
Note Paragraph (4). A motorhome towing a vehicle is definitely a "combination of vehicles". If you can stop your rig within 40 feet from 20 MPH, no auxiliary braking is required in Montana.
Most states, and the FMVSS, have a similar braking performance standard.
I have never seen a "list of towing laws" that is truly accurate when it comes to laws regarding the towing of passenger vehicles behind an RV!
