    Anybody in the group make a DIY CO2 tire inflation system? Pros/cons? Things you'd do differently?

    I have a hard time justifying the $500+ for a Powertank. The only thing I can see as a potential problem is the regulator freezing but I don't know how much of an issue that is for real world use.

    I built one, but haven't yet filled it up. I have it sitting in my front room.

    I debated buying the mounting bracket for the powertank, but don't like how you drill through the wheel well for mounting.

    I'm looking to get their sport bar mounting bracket to save even more floor space in the trunk

    Powertank is an amazing product. I had one with my last crawler and I was bummed to let it go. It was kind of a package deal when I sold it. I got a turn key price though.

    I had a manifold on it to run my ARB lockers and also had the ability to run whatever else I wanted. Having instant pressure to reset a bead was nice. For typical airing up, I still used a compressor most of the time since it got trailered the majority of the runs I went on. If it was the last day of wheeling and I was going to use the Jeep for local transportation for the rest of the camping trip, I’d air up with the powertank. Nothing beats the powertank for airing up quickly.

    That being said, I have a smittybilt compressor. It smokes the two viair compressors that I’ve had.

    Yes it's pretty new. Glad I could help somebody out!

    I've already got quite a bit of mods ready to go... just need my JLUR to arrive!

    I have one that I built. Use it all the time. I bought the mounting bracket from powertank and drilled through my wheel well. I love the setup.

    I bought the tank from a local welding supply shop. I ordered the hose from Amazon, and picked up the air chuck from Home Depot. I already had the regulator. I think if you order everything from Amazon, you can get it for around 150-175 bucks. There are a couple of YouTube videos if you search DIY CO2 tanks which will give you directions and links to parts.

    My tank is a 15 pound tank. It was about 45 bucks cheaper than the 10 pound tank.

    I put together my own with a 20# CO2 tank and adjustable regulator from eBay.

    Used 20# tanks on CL are very inexpensive ($25 to $50) in Colorado. Apparently people use them to help plants grow faster in their basements. And $10 to swap an empty tank for a full one at a grow store.

    Buy the majority of my CO2 tanks life is in my kitchen making seltzer water or root beer, or carbonating grapes and oranges me

    Would like a good mount for the 20# tanks...

    I live in TX. During the summer, it is HOT and HUMID. I talked with a friend and he indicated that in TX, it isn't a good idea to do CO2. He said that the regulator froze over the couple of times he tried to use it.

    Is this an issue with the regulator? Or is this something that I have to deal with living in TX?

    I know that PowerTank says their regulators will never freeze. If true, how to they address this issue vs universally used 150 PSI regulator that is recommended for DIY systems.

    A bit off topic but almost 40 years ago I worked at a wholesale a/c & heating supply company in Texas. If our 3/4 pickup tires would get low, we'd use the most handy item which would be tanks of freon. I would not recommend it but always wondered about that idea.

    Tempe is hot, but not necessarily humid? Have you had issues with using this during the summer? I'm trying to wrap my head around usage in a hot AND humid area.
