Great product.

I just installed these, will update if things change but for now extremely satisfied. 35' Class C MH with 4-down toad. I do like the anti-theft rather than flow through sensors (only ordered AT so I can't say with certainty). The anti-theft sensors aren't bad to install--you don't have to use the tool. I was concerned of course about something else to keep up with, if we had a problem and need to add air and don't have the tool, all that. The anti-theft device functions as a dust cover you can unscrew by hand. Even these are fairly large, and bound a bit on my hubcaps, so had to modify the extensions just slightly. The flow through would be really big and I doubt they would work well on a dually or with hubcaps. Other thing is they do stick out--and I can see someone walking by and unscrewing them just for grins if you didn't have anti-theft.

Overall installation easy and intuitive. And yes, can use the tow-vehicle or the toad individually or both together. Very easy to tell the monitor to disconnect one or the other. We use the MH quite a bit w/o the toad, and the toad is our everyday vehicle, so I plan to leave the monitors off the toad most of the time (it has its own internal sensors when we are just using it). Really easy to just screw them on before a trip when setting it up and should be checking tires closely anyway.

I am very pleased with this system. The programming setup is reasonably easy. I used the off the vehicle setup option (2). The unit does a great job of keeping me aware of the current status of my tires.
I would buy this unit again.
The range of this unit is very good. I do not have any repeater or range extender. I purchased this TPMS for our 30' Class C motorhome, tow dolly, and towed vehicle. Total length is 55+ feet when towing. The unit reads my tow dolly sensors when it is stored behind the shed. This is 90+ feet away and it also reads my towed vehicle while it is in the garage. This is 75' in another direction.
I recommend taking the time to use the numbered stickers which are supplied (place them on the sending unit not the anti theft cap). Once the stickers were in place I coated them with clear nail polish to help protect them from the weather. Once the programming was done and the nail polish dried all I had to do was install the numbered (1, 2, 3, etc.) sensors at the proper tire position.
All TPMS' take time to acquire the sensors when you turn them on, therefore, do not expect to turn the unit on and drive away. I recommend turning it on before you go out to clear your site and stow your gear. Sitting waiting for all the sensors to respond is like watching water boil and just as productive.
Be aware that weather temps impact your tire pressure. These units will sound a warning if the impact of weather temp changes is sufficient to trigger an alarm. This is a good thing in the morning before you get on the road.
Also, if you decide that you want to change your standard tire pressure due to axle load or whatever remember to put the new numbers in the TPMS before you hit the road (do not ask me how I know).

I've only been an RV'r for the past couple years. About a year ago a friend installed a similar tire pressure monitoring system on his Class B RV, which alerted me to the potential for disaster due to having an RV tire fail at highway speeds. Subsequent trips in my Class A (without TPMS) were more stressful as I kept wondering how my tires were doing. We're planning a multi-week, multi-state RV trip, and I finally decided to address my concerns. After some research, I decided the EEZTire TPMS system was the best option, and I am very glad I chose them.

The installation/programming instructions were excellent and easy to follow and perform. I did all the programming myself (off the rig), but enlisted the help of a local truck tire shop to physically install the sensors after The only complication I had was the rigid valve stems on my RV were not readily accessible (especially the inside dualie wheels), so for about $100 I had the tire shop replace all 6 stems with ones I can easily access (the inside dualie was fitted with a longer stem that protrudes through the outside wheel so I can get at it without having to crawl underneath the rig).

So far, so good. The readings started showing up on my system within just a few minutes of installation and are giving me a complete picture of what my tire pressure AND TIRE TEMPERATURE profile looks like on my rig. The peace of mind the continuous monitoring gives me while driving is worth the price of the system!

UPDATE! 10/6/17. As far as I'm concerned, the product has proved its value...soon after installation (and the DAY BEFORE leaving for a 3 week RV road trip), I fired up the rig to pack and prepare and noticed 63 PSI (ideal is 95) on one inside "dualie", and no reading at all on the other inside dual. I assumed perhaps faulty sensors, but took the rig back to the truck tire/installer to be sure. The 63 was the correct tire pressure reading, and the "no read" tire was, in fact, completely FLAT! Turns out the installer hadn't sufficiently tightened/sealed the valve stem extensions. Had I not checked, I would have been on the road with one seriously under-inflated dual and one completely flat! The fact that this particular situation occurred as a direct result of installing the TPM system on my rig is not the point. The point is, prior to having the system in place, I was completely BLIND as to what my real-time tire pressure situation was. A loss of tire pressure can occur at any time, and for any of several reasons...and not not knowing it when it happens is dangerous. Thankfully, I'll not be caught unaware now that I have the TPS system installed on my rig!

Two weeks after installing was pulling our 30' travel trailer with my dually. Was doing 65 mph and got alarm that front left truck tire was loosing air rapidly. As I searched for a place to pull over it went from 80 PSI to 70 then 60 then 50 and 40. I stopped on the shoulder, was lose and uneven. Not a good place to change a tire. Pressure loss slowed dramatically so I limped down the road to a country convenience store. The valve stem was leaking were it inserted into the rim. Swapped the tire on a flat parking lot and drama was over. Without the TPMS I would have been oblivious until it got really bad. Might have ruined a tire or much worse. Bought this after I bought my used dually, drove it home at 70 mph and later found an inner dually tire was completely flat on that trip. Lucky it didn't blow. That incident and the infamous "china bombs" on new trailers had me worried. Now I no longer have to manually check 10 tires each time we travel. Despite the automated alarm capability we keep an eye on pressures and temps on the screen as they rise depending on speed and weather. The TPMS is like insurance; if it saves you it's money well spent, if you never need it then you wasted your money. No complaints on the product. Bought after a lot of research. Expensive but worth it
