This is definitely a concern of mine, I have had tires blow on my travel trailer and never knew until kind people flagged me down. I am hoping several people have had success with both systems working properly together before I make a final decision. Thanks.

I have used Crossfires for 8 years on my Journey. Had a pro install them but replaced one myself. It is very doable but you have to plan your approach to the inner dually so you can connect the valve with the hand you are comfortable using without actually seeing the valve. The dial starts to show red if you are one psi over the Crossfire designed pressure and shows full red at 5 psi or over. If you never see red, then it is highly likely your device is defective. I check them before setting out and at every stop to drain the dog when I circle check the coach. I would not be without them. Previously had a TPMS that was a PIA when topping up tires and with the sensors leaking frequently. Crossfires eliminated these issues and in my opinion are grossly superior. Have never had a tire failure in 80,000 miles likely in part because you are able to quickly and easily identify the tire pressure in the duallys and adjust as necessary.

I put the crossfire system on my 2000 Damon Ultrasport. You don't have to remove a tire, and with normal dexterity, and mechanical ability, anyone can install them. I have the 110psi on mine and haven't had to add air after 4000 mi. Highly recommend.

I have crossfires with the dual TPMS mounts - couple of years now and no problems. Besides the obvious benefit, having one easy to get to port for adding air is my favorite feature.

My tires will vary in temperature based on wind direction, sunlight and air pressure.

I also shoot my brakes on occasion, especially if I had a hard stop prior to checking the temps and never noticed any effect on the tire pressures.

If I was you I'd get an IR gun and keep track of your tire temperatures before I spent any money on that system.
Arch, how did you determine your " warning" temperature using the gun ?

Great question!
TPMS has twice warned me early, while rolling, and saved 2 rear tires for me.
Once one tire on a dually goes down, without a warning, the other tire gets cord damage making it useless.
If a TPMS sensor leaks, it will still give you a warning.
Crossfire just shows, after you stop, that a tire leaked. No more, except for any collateral damage!

I have used the Crossfire and a TPMS for years on my F-350 and again when I purchased my Tiffin. Along with keeping both inner and outer at the same pressure adding air is easy. You hook to the Crossfire and air goes into both tires at the same time. I will not be without the system.

I have used Cross-Fires on both coaches I have owned since 2005. Not always happy with the way they are mounted, can scratch the chrome wheels, but the video seems to have that problem licked. They work as stated, shift air back and forth between the wheels, indicates pressure, and allows one point fill up of air. I would not be without them and I am sure that they add life to the tires.

I guess I'm on the other side. I don't think the Crossfire is necessary. Both the rear dual wheels are bolted to the same brake hub and the pressure rarely differs by more than 2psi.
Next time you are at a truck stop take a look at how many class 8 trucks have one.

I would prefer a good TPMS system to monitor tire pressure while driving, not just when stopped.

Also running Crossfire on my Newmar. It was already installed when I purchased the rig from previous owner. I've added a TPMS. This thread has been very informative.

Thanks for the response, so far no one has said they would remove the crossfires and like the benefits.

Yes. My homemade wrench will allow me to not have to take the wheels off. I have big hands so while it's a slow process I have done it a few times.
All it is, is a long 1/2 inch wrench heated and bent at the open end. I had an extra long one that I sacrificed.

Crossfire equalizing tire valve

I also use the crossfire system with individual valves for the TPMS sensors. Allows you to monitor each tire individually with a common valve to add air to both. They work well with the TPMS sensors.Click image for larger version
