What trailer brake controller are you guys using? Is there a wireless unit that doesn't mean you have to run wires the full length?

I only tow one trailer (with electric brakes) with my coach, so I installed a simple Tekonsha brake controller under my dash. There is an unused blue wire in the harness that originates somewhere behind the driver's side panel and goes to the back, near the driver's side tail light, that can be used for that. I couldn't find it, or didn't know where to look for it at the time, so I ran a new one under the coach, inside the frame.
Works for me.

BTW, One of the worst RF noise offenders are vehicle electronics. Every piece of electronics emits RF noise. A kids electronic toy needs to pass a higher standard than a piece of office equipment. The reason being is the Gov. doesn't want to deal with interference to radios and TV's in homes. In commercial venues not so much. However vehicle electronics are not required to pass any type of RF emission standards.
The amount of electronics in vehicles and the amount of RF interference they spew is incredible. We had lots of issues with Transit buses and agricultural equipment. The equipment manufacturers could fix it with a couple of dollars more for RF filtering on the wiring, but its not required on a $400,000 bus or a $750,000 combine so they won't do it.
So if your wireless trailer brakes failed, it maybe because of the guy planting corn in the field near you... and there isn't a damn thing you can do about it.

The Tekonsha brand has proven 100% reliable over 12 years on my Tahoe. I have an enclosed United tandem axle car trailer and never a controller issue. The harness also provides tail/ running/ plate lamp power, brake and turn signals and aux 12V power if you want. You can add an isolator for $70 in the aux line and never worry about one vehicle or fault killing the other while parked. The aux can keep your winch or toad battery topped while driving. Science!

Bruce, we have complete control over the sites, and the dishes are high enough that ground based stuff isn't a great concern. As to 900 MHz, we dropped it when we dropped analog carriage. It worked well for decades but suddenly was opened up for part 1`5 stuff. My old 340 car had copper spark plug wires... it would wipe out everything for a block. Replace the coil with with resistance wire, and cut the noise by nearly 20Db... no longer a concern.

930 - 950 has several channels specifically for STL links. Either composite centered on channel or discrete a coupl hundred KHz each side of center. The discrete would go further but could get you into phasing problems between channels. These timing errors cause a loss of signal when a mono listener picks them up. We beat that by using matrixing of the two to transmit. This keeps the two in phase at the expense of a bit of separation.

When Nissan (Datsun) first installed EFI on the 240 Z, they had no
suppression coming or going. They were notorious for just stopping dead in
their tracks, and not restarting. After they were towed in, you would climb
in, turn the key, and they would fire right up and run as well as ever. A
scan would reveal nothing, no stored codes, nothing. So you would just
scratch your head, exclaim "Whiskey, Tango, Foxtrot", call the owner and
tell them nothing was wrong with their car, try to justify charging them
for your shop minimum. Wasn't long until you had one P.O.'d customer. Took
a model year before Datsun figured it out. Ordinary close by radio
transmissions were found to be the cause. Don't know what they did to fix
it. Some kind of shielding, I reckon.
