I've just bought a Cruiseliner. It will be towed by various vehicles on work trips and I'd like to know if one of the portable brake controllers that sell for about $300 might be suitable that can be transferred when changing vehicles will do the job. The van currently has a 7-pin plug and I was hoping to keep it simple and staying with 7-pin if possible.

Something like one of these:

Hi Luke, question, do any of the “other work vehicles” tow anything else that may require a brake controller? If they do, IMHO, it would be better to install brake controllers in all these vehicles. I can see that with this type of portable system, it would be too easy for the “plug” end of the unit to become damaged. Also, if the unit was on one of the “other” vehicles that was potentially out on another job, and you needed it for your van, it may not then be available.

thanks Macca, my Cruiser has a controller as it usually pulls a 1.4T flat top work trailer and it's set up with a 12-pin and break-away etc but my Triton single cab doesn't and other ones can be cars belonging to staff and crew and we even get some loaned 4WDs. so maybe I'll put controllers on my Triton as well and save the portable unit for the other more random ones.
I agree with you that having more plugs down the back all connected to each other is not the best solution but we've got pretty good at protecting trailer wiring from doing this for years and we carry spare plugs and solder gear so can replace the plug ends and/or repair and replace the wiring easily.
Thanks again for the reply.

Simple answer is yes if installed as per the instructions. Looks like they have really bumped up the price over the past year - mine was $200.

as I find out more - so my Cruiser has a 12-pin plug and controller so questions:
(1) am I right that I can plug the 7-pin from my AVan into this and it'll work (as long as both are correctly wired - and I'll check that).
(2) are the the extra 5 pins in the 12-pin plug are only needed to charge the break-away battery?
So it looks like the blue wire (pin 5) wires in the 7-pin plug is the control wire for the electric brakes.

(1) Yes, the 7 pin plug fits into a 12 pin socket. It's the other way around that does not work.

(2) Break-away battery? What is a van that small doing with breakaway brakes? Trailers with a GTM of 2 tonnes or less do not need breakaway brakes. The other pins may be used for house battery charging (pin 8) or powering the fridge whilst travelling (pin 9.)

The only thing that concerns me about your proposed kit is it contains a synchroniser type brake controller. Most of us (and manufacturers) are steering clear of those these days. We are using proportional types. They provide better braking characteristics and are generally set and forget devices. The synchronized types only offer full braking current no matter whether you are braking lightly or in an emergency braking situation. They are a pain in the but when you are driving in traffic and only using light braking. Drivers often reduce the gain when they are in traffic. When they do that they no longer have full braking during emergency situations. This may not be too much of a problem whilst the lightweight trailer is being towed by heavy 4WDs. The following graphic illustrates the difference between the two types.

thx Nomadic Navarra.
The 12 pin plug on the Cruiser is for a different 1.4T flat top work trailer (potential total weight is 3.5T). thx for the thoughts on synchronised versus proportional. I've ordered one of the simple ones and will see how it goes. Hopefully "simple" might do the job, most of our driving is on country roads but if it doesn't go well I'll re-read your info :-)

While dearer than the others, it sits on the van and works independently.
