Thanks all for the information. It appears (we didn't "order" this truck) the truck which the dealer had on the lot . This truck has everything - the new all around cameras, onboard everything built into it. Just not the stupid $50 sensors - which is what it would have cost if I ordered the truck to be built. Here's the catch - $300 plus tax for the sensors, then pay someone else at a tire place to install them on the new trailer, an additional cost.
Here's the problem - our new trailer (Outdoors RV Manufacturing) comes with metal stems which is their new upgrade. This unit is meant for off road which is why they finally upgraded to new stems. These chevy ones are rubber. so for the same cost I can purchase an aftermarket tpms system which also has temperature readings and either wire it or I see there are now solar ones that use an app on your phone. It will cost about the same as the other way. Geez nothing is ever easy, right? thanks for your help
