"Borg Dually Valve System" or "Crossfire"?

I would like to hear pros and cons of using either system on my 30FW with dually wheels. I have to do something since it's a pain for me or my wife to check and fill tire pressure.

Since you do not have TPMS sensors on your stems, you could use the Haltec screw on extensions like I did. They are unique as they don’t have pressure in the stem except when you press the valve to check the pressure or air up the tire. There is a metal rod down the center that activates the actual valve stem when depressed.

They screw on, but you need to remove the outside tire to install (unless you have extremely small hands). The benefit is the inside tire doesn’t need to be removed and broken down to replace the stem. The 5 11/16 length is perfect.

I have the Crossfire system on my duals. I love them. Quick look and you know if there is an issue or not with pressure. Single point fill of either tire is a great benefit.

I use TPMS that monitors both of the duals individually through the Crossfire system. I believe well worth the money.

That's an interesting concept and minimizes connection leaks.

I also used the Crossfire and it is great. When I went to pickup my new Isata 5 at the dealer I noticed the tire pressure was 10psi below what the door jamb details specified. When I told the service shop, they came back stating they had to find someone in the shop with small enough hands to get between the duallys, not to mention crawling underneath, in order to fill the inner wheels. That was enough for me as I had ZERO interest in doing that to check the tire pressure.
A short bit of research on this forum led me to Crossfire and I am glad it did. I actually installed it myself, although you definitely need to be a DYIer for the project. I can't imagine the install would be much for a good shop. Once done, you fill inner and outer wheels from one spot. And the the system keep both inner and out tire pressure exactly balanced. And there is a check valve that keeps both tires from failing if one gets a major leak. That, along with TPMS monitors on each wheel, and an indicator in the driver compartment, and you can monitor not only each of the six tire pressures, but their temperatures. I wouldn't have duallies without both. In fact I have a new Force on order and already have the Crossfires ready. So, in summary, Crossfires with a good TPMS on each wheel, and you are way ahead of the game for road safety. BTW my Isata 5 came with a nice TPMS. Sorry I don't remember the make, but support was quick and efficient.

#1: have you checked Cateye? That is what Fury wears. Designed by man who invented Crossfire & sold co. Said to correct weaknesses of Crossfire.
#2: Wolf recommends covering stainless steel woven lines with plastic cable wraps to protect your highly polished aluminum wheels, if you have highly polished aluminum wheels.
#3: RVing with heavy equipment is technical & often requires incurring expenses or the duty to perform chores. If these become burdensome, folks quit the hobby.
#4: It is the pneumatic tire that is the root of the problem. Filled with pressurised air that leaks out & leads to tire failure.
Every device like these, TPMS, spare tires, sealers, road service policies, etc. all are trying to somehow deal with the shortcomings of the pneumatic tire.

How is it different and better than the Crossfire system.

Over the last 11 years I have broken my right leg, shattered my right ankle, broken my left arm, shattered my right knew, broken 3 ribs and broke my back, at different times..... I could stay home and sit on the couch but I chose to buy my rig and venture out instead. The more things that I can do to make my life easier, the better.

I got my crossfires from Donley Enterprises (Ed Donley). I spoke to the manufacturer when I was doing my research and they recommended Ed.
800-774-1944 or Ed’s cell which he doesn’t mind at all, 817-905-6969.
He was very helpful. Yes, I installed the webbing infused tubing over the Crossfire hoses, per Ed. I got the tubing, and recommended antiseize on Amazon. You have to leave the plastic wheel covers off after install of the Crossfire. One creative gent on this forum actually modified his wheel covers. I thought they look fine without wheel covers and didn’t want to go to the trouble. If you search this forum for “Crossfire” you will probably find that original post which was very helpful.. I got the 90psi version, even though the recommended TP on my Isata-5 was 95. Just leaves a little wiggle room.
If you don’t know yet Crossfires are manufactured by Dual Dynamics. Here’s their website. Home - Dual Dynamics
They have some decent how-to and informational videos.

I got mine from Donley as well. No web site. They shipped them to me and then finally billed me three MONTHS later. I almost forgot what the bill was for! Great people to work with.
