TPMS and NAV for use with 35K Bounder

Pressure pro for the coach and the toad.

The DW has a TomTom that I hate. I use the Co-Pilot RV app on a tablet along with Waze for traffic. Whatever GPS you decide on, make sure it has a mode that takes into account the height and weight of your rig.

Always pick "fastest route" vs. "shortest route".

We recently purchases the TST TPMS and used it on a round trip from NY to FLA and had no issues. This is the first TPMS I have ever used so I watched it like a hawk for the first 500 miles but then promptly forgot it was there. It was nice not having to go and check tire pressures everyday.
As far as a GPS, I have been using CoPilot for 3 or 4 years now. It is a paid app so that will factor in. Being that I can run it on an iPad makes seeing it much easier too. Copilot gives you height, weight, propane restrictions as well.

I also use TST for TPMS and it has been trouble free for four years. I use the Co-Pilot app for my navigation. It has an RV option, doesn't need data to operate once you download the maps and only cost 9.95 at the time I bought it. I like that I can use it on my tablet in the RV which gives me a nice 9" screen that I can see and read without my reading glasses. I've been using it for about 3 years now and it works just as well as any others that I have had including Mio and Magellan.

We like TST for the TPMS, and we have a Garmin 760 for the nav.

I have EEZtire. Been trouble free for going on 3 years now. Batteries are a cheap standard type and fast and easy to change. Use Sygic from Play Store on my Android phone for GPS. Stores maps on phone so does not need reliable cell signal to work. Used to use a Garmin but cell phones can upgrade you to new tech better than a 'fixed' GPS box can.
