I am pulling a 36-foot 5th wheel behind a long-bed pickup. Will the sensors have enough "transmit" range, or do I also need a "repeater"?

We have a travel trailer that is 35' from the tongue to the back, that we tow behind our Yukon XL 2500. The range is fine. Being that ours is a tow-behind and your question is about a 5th wheel, I think it is safe to say the distance from the monitor in the cab to the tire sensors is farther than what you will end up with so my guess is that you will be OK.

I have a factory install on my ram can I just extend it to include my TT ?

You can use our system on anything that you are towing including cars with factory installed TPMS systems. They do not conflict.

Hello, question for eez tire tech support regarding the color monitor. users complain about the dim color displays. did you upgrade your product?

The 518c is an upgrade to the E618 system. Keep in mind that the new 518c system monitor is easer to see in bright light. The 518c sensors and monitor is not compatible with older T518 T515 or E618 systems.

I have a small trailer and only need 2 sensors is it possible to purchase only 2 sensors and the monitor?

Probably if you contacted the company directly
