Does anyone have any feedback on the current systems?

I had a system a few years back, but sold it with the boat. My trailer is a tri-axle, and it's about 45' from the wheels to the dash. While the screw-on senders are easy to install, I'm concerned about the stress on valve stems and water intrusion, so maybe the internal-mount systems make more sense, especially around salt water.

I bought this in September for my toy/racecar hauler; and LOVE it.

It comes with a repeater, and it works great.

If you don't have solid metal valve stems, you will have to change out to such, but that's not a big deal. With a portable bead breaker, you could DIY with the wheels still on the trailer (one at a time).

Thanks, Brian. I assume that the sending units are sealed, so dunking them at the ramp is not an issue?

I just bought this for my 450. Hope to get it installed soon.

Looks similar to the system Sydways has, but everything stays attached to the trailer?

This allows me to see all tires and temperatures at the same time and looks better IMO. The only thing that stays on the trailer are the tire pressure sensors. The receiver wires into the truck. You can name different trailers and have them all programmed and it recognizes each trailer differently.
