Auto tire inflation system

I bought a new Landoll trailer, and was wanting to add auto tire inflation. The trailer is already prepped for it (axles already drilled), but I need to buy the kit and install it.
What is the best system in the market these days?

 

I think I’d rather have a setup that ties into the air system. Those do seem like they would work well on a tractor, but with a trailer with 17.5 tires, the Halo would cover the whole wheel.

We already have one Landoll with the Metior system on it, and it works fine, other than it has a small leak somewhere that I have yet to find. The low pressure light will come on for a few minutes after the truck sits all night. It’s also a few year old system, and was wondering if there was something better now on the market.

 

I’ve been doing research, and I think Tire Maax Pro is the best setup. Everything I’ve found about them though just indicates them working on Hendrickson axles. My trailer has Dexter axles. I’ve sent a message to Hendrickson about it.
