Roadmaster InvisiBrake Flat Tow Brake System - Preset
The InvisiBrake system vacuum pump was too weak and slow to respond . I installed an external vacuum pump from Summit Racing which maintains 22"of vacuum on the brake chamber at all times ,the same as when the Ram engine is running . I installed an isolation valve on the Ram manifold vacuum line and a momentary test switch in the Ram to simulate the coach brake lights being on . That way I can take the Ram for a drive and set up the brakes as they should be.
Read the instructions and only use the trailer video/s as a guid!! Install was tough but doable. Take your time if you want a clean install. Lastly, the kit comes with updated check valves. The video will tell you that the "red side" faces the engine. That's not true if you are using the "black side" check valve. The black side faces the engine while the red is opposite. I wasted several hours troubleshooting a stiff break pedal when in reality, I had the check valve installed just as the trailer video explains it. My bust for trusting the video and not reading the install instructions fully.

Roadmaster Even Brake Portable Flat Tow Brake System - Proportional
Very touchy on where it is sitting on the floor in front of the seat. Must be lined up almost perfectly. Heavy and clumsy to get in and out and connected to brake pedal. Need to add an on/off switch to the power line on the controller otherwise it is transmitting a signal on Jeep brands all the time that interferes with the remote key lock. Quite disappointed with hit and miss braking operation while in use and sending braking signal to driver when it is not braking.
I bought a complete flat tow parts fir a jeep wrangler. I decided I could install myself. Your installation videos made it nearly a piece of cake. From a quote I got from a RV service business, I saved several thousand dollars installing myself. etrailer is the place to for your RV needs!

Roadmaster Brake-Lite Relay Kit for Towed Vehicles
Evidently Roadmaster had made some slight alterations from the depiction, for the better. The fuse wiring was a spade end with two fuse holders built in. The holder closest to the spades was for the original circuit and the other for the new circuit. This was very handy. I had watched the installation video and thought it would be fairly easy; therefore I attached the terminals to the green, black, and white wires before even going to the CR-V. I did however purchase different spade connectors as I thought I may want to remove the brake relay switch in the future for another vehicle should I trade. Also the yellow connector is quite large and the video showed bending the wire over itself so that it would hold on the smaller wires. This was a wise decision. What was the problem was the wiring in my CR-V. The video showed similar size wiring from the brake switch. What I found was smaller wire, loomed very close to the brake switch. Evidently Honda had made some modifications. I believe the wire was 22 gauge and there was no real way the blue or yellow connectors would have worked. That said, after disconnecting from the switch, stripping the loom back to get some exposed wiring, cutting and using the 22-16 gauge connectors, drilling a hole for the ground screw, etc. the switch worked perfectly. I did vary the fuse location from the 7.5 Amp #29 Occupant Detection System (ODS) to the 15 Amp #28 Washer as I figured it would less likely interfere with any operation.

Air cylinder , controller and LED light installed . Aside from the base plate bracket not lining up with the upper bolt holes I would give it 4 stars . My son in law is a master at solving mechanical issues .

Roadmaster BrakeMaster for RVs w/ Air or Air-Over-Hydraulic Brakes - Proportional
This braking system does what it's suppose to do, smooth proportional braking between motorhome air brakes and the tow vehicle. The only reason I did not rate at 5 stars is that there is a slight misalignment of air cylinder mounting bracket and 2022 Jeep Gladiator brake pedal.
The install on my Ford Maverick is clean and functional, so this is more of a customer service review... excellent customer service! During the 4-day towing set-up install, the forecast was for freezing temps and my rig was not winterized. I called in mid panic and the motorhome was moved indoors. A few months after using the tow set-up, a minor problem developed. I called and the CSR apologized and said, I can see how that might be frustrating, and a replacement cable (slightly longer) was sent free of charge.

Roadmaster BrakeMaster for RVs w/ Hydraulic Brakes - Proportional
Kit fits great! Hooked up a 2004 Workhorse to a 2002 Jeep Liberty. It might be preferable to be handy with some advanced mechanical skills and tools to install this efficiently. Directions are great but you do need to figure out your own locations for certain items like the break-away reservoir, compressor, routing lines and wires out of harms way, but not bad at all. Parts are great, everything there but added a couple different wiring splices of my own.
Your customer service leaves nothing lacking, and this follow-up from you is so out of character for the many web sites I have purchased from over the years. I am impressed by you and your company. I bought the tow bar and the brake system for my Equinox, and installed them my self (I am 70 years old) - and with your provided instructions and video, I had no problems (even though I was surprised by the number of parts and detail that went into the assemblies). Both systems have worked very well, with no problems. I am completely satisfied with them, and have told my friends and traveling acquaintances about your company. Thanks for your follow-up!
