They tell me that some places require aux brakes on any trailer over so many pounds, (Usually something like 2400) so you may need towed brakes by law in some states..... I'm not an expert on this so you would need to check it out.
However Physics... That I did study, and I can tell you this,,, brakes on the towed will make is so much easier, and safer, to stop in a hurry when you have to... They will also reduce the wear and tear on your MH brakes which in and of itself can be a budget saver
I have done a lot of resrearch, much of it here in the forum, and have come up with two suggestions for towed brakes. Both of these systems have an advantage of being totaly transparent from a towed driver viewpoint, there is NOTHING to install/uninstall/forget on the towed, it's all "hidden"
For Mothor Homes with Air Brakes, (And you can install it on vehicles w/o air brakes too if you wish) if it will fit on your towed M&G is the best brake system... This is an air brake system and uses the tow vehicle air to power the brakes. It would not fit on my towed
Unified Gear, This is an electric brake system, but is also porportional and progressive (whatever that means) This unit installs inside the towed but the power unit is hidden
Both systems use the towed's own brakes, M&G adds an air cylinder next to the vacumme assist, it "pushes" the master cylinder as though you had pushed the brake pedal, The Unified Gear uses a cable, like a parking brake cable to PULL the actuall pedal down
Other systems are Brake Buddy, Brake Pro, Apollo Brake system and Brake Master. All of these are pedal pushers,
Brake Master is an air brake system, it mounts to an adapter plate under the driver's seat and to the brake pedal. You have to remember to put it in place every time you tow... (Remove when you drive)
The rest are electric systems, Most use an intertial sensor so they work like surge brakes, but again you have to remove them when you dirve and remember them when you tow. Brake Pro is very pickey about it's power supply. and all but brake master use towed power
(Note Unified Gear uses towed power too... I"m having my towed modified so the MH can keep it charged)
I went with Unified Gear, it's more expensive, but I believe it's worth it
