...For a system that can be easily used on two different vehicles, that will be much, much more budget friendly than any of the systems already mentioned, look no further than the Readybrake.
Just can't beat it, IMO - Simple (one time) installation in towed vehicle of nothing more than a cable from brake pedal up to front bumper, only costs $60 more for same cable to install on a second vehicle, so you can tow either vehicle and use the Readybrake system. Simple, no-nonsense, no electronics cable operated system that simply works. Costs SIGNIFICANTLY less than the other systems mentioned, will work on almost any vehicle including hybrids (unlike M&G). And, almost all parts to it that could wear out eventually, could be found at any hardware store for less than $20 (and easily installed by the owner, no need for expensive labor). No need to wait weeks for the company to send you replacement parts like is the case for most any other brake system.
Now, it doesn't give braking quite as smooth and truly proportional as an air operated system like AF1 or M&G that works directly off of the MH's air brake system. If you have a MH equipped with full air brakes, M&G or AF1 is probably the best option (although much more expensive than something like Readybrake). However, if you have a gas coach or one that doesnt have full air brakes, then the Readybrake makes a lot more sense, IMO.
