I use tiretech, tp7002. Used it for several years on TT and now on greyhawk. Additional sensors on car dolly when in use. Range hasn't been an issue which I've heard others can have with TTs. It is a pain to add/remove sensors but easy to adjust existing. Accuracy is 2-3 psi. I have them on both dually wheels in the back, which can be difficult to put on trying to fit hands back there. I tried some valve extenders, which could be very helpful, but getting the right curve to fit with the aluminum wheels caps was too much trouble unless I bought expensive ones.
