Question Location of Spartan integrated TPMS antenna?

[MarkMaxPayne]

I have yet to get Spartan's TPMS display to work properly on my 2023 Newmar New Aire Spartan K2 chassis for my TOAD vehicle. I purchased the Spartan TOAD TPMS wheel sensors (through the dealer), had them installed (through Les Schwab as the dealer didn't deal with TOAD tires), configured the Spartan TPMS settings to tell it that I have a TOAD vehicle and the serial numbers of my sensors on my TOAD vehicle, and...it can never find the sensors. It also sometimes loses connection with the rear tires on the passenger side.

I have seen other threads mention that the placement of the Spartan TOAD antenna used by the TPMS may be at issue and that some have even had 2nd antennas installed even to read the rig's tires properly let alone those on the TOAD vehicle. That said both my dealer and local Spartan service centers (Portland, OR area) haven't really been helpful (both--we don't do TOAD tires).

If anybody does have this working, I'd love to know. Also, anybody know where I can find the TPMS antenna Spartan / Newmar did install? I assume it is between the frame rails in one of the bays, but don't feel like removing panels between the frame rails in the basement to go hunting...

Best,

The antenna is located under the chassis towards the back of the coach between the frame rails. On my 4369 there are actually two one up front and one back of the rear axles.
I still have issues with various sensors randomly dropping offline for periods of time, which is why I never installed sensors on the toad and use TST TPMS

Thinking about stopping at their homebase in mich. this fall. The outside drive wheels are dropping off line. Thinking it must need a signal booster or something.

Dang....All these "hi-Tech" systems on these Coaches seem to create many issues for the owners! To me, that's sad! Newmar & any other manufacturer that installs these "doo-dads" should insure that they work, so you folks don't have to experience the frustration, etc!
Fortunately or unfortunately, My Canyon Star doesn't have a lot of this "hi-Tech" stuff!
I do have a TST 507 TPMS system that I am totally happy with, and it works so well, I do not even have to have a booster antenna installed, for it to receive signals from the duals, and the toad.
As a suggestion, & maybe to end some of the frustration, you might look at a "TST System", and forego the factory installed system!
Technology is wonderful when it works properly, but too frustrating for me! Re: KISS formula!

At times I do miss the "simplicity" of the Canyon Star. Many more manual systems that just worked as intended.

Friend of mine with a 23 London Aire was having problems. He moved the antenna that was over rear axle/between frame forward to the front rear axle, and angled it a little differently than installed. Said working fine. Sparton was scratching their heads at the problem.

Looks like Newmar has finally found a fix for the TPMS issue regarding lost signal. The Tech moved the antenna on the chassis (down) and signal appears stable now.
One more item to check off the list.

Interesting, can you elaborate? When I was at Spartan they wanted to install external sensors on valve stems instead of replacing batteries on the internal sensors. Their logistic was not only cost savings on battery replacement but that signal was more reliable.
Since I have no confidence in their system, I run TST in addition. I wasn’t willing to give up TST so they replaced internal batteries under warranty reluctantly

Was interesting to see the TST display while we were at Spartan getting the run flats installed on our Superstar.

I talked to a couple techs about it and they said they were all pushing to get rid of the internal and just install the TST as they build the chassis.

Nice to hear they may have a fix though.

When at Newmar Annual Service one of the items was the outside drive wheels loosing TPMS signal. The chassis guy at Newmar relocated the antenna on the Chassis “down”, not exactly sure what that means nor entails.
However the end result is a steady signal the last 700 miles or so.
This appears to be a fix Newmar Service has worked out with the chassis supplier engineers. Enough people have complained.
Spartan Chassis in my case.

Previous recommendations from engineers, techs, Spartan have ranged all over the place.
This included the folks that built the TPMS system. They had no solution and referred me back to Spartan.
