Let me know when you find a regular pen type tire gauge that will read 5 psi correctly and allow for accurate deflation. There are 2 valves not one and no not just any gauge will work.
OP Check here https://www.etrailer.com/tv-install-...ner-f4135.aspx Oh and here https://www.etrailer.com/Vehicle-Sus...one/F4135.html

http://riderite.com/-/media/www/ride...lManual_EN.pdf
Specs: - Load-leveling capacity: at least 500 lbs (at most 1,000 lbs)
- Coil-Rite springs will not increase your vehicle's weight-carrying capacity. Do not exceed the manufacturer's recommended weight limit.
- Adjustable air pressure: 5 psi to 35 psi
- Limited lifetime warranty on air springs
- 2-Year limited warranty on hardware
OP Talk to your installer and read the instructions for your setup and experiment I know I change my air pressure depending on my tongue weight and truck weight etc.

I found a low pressure dial type gage at my local auto parts store. A dial gage will give you a more accurate reading than a pen style gage.

I would think the best gauge (for everything nowadays) would be a digital tire pressure gauge. They are relatively cheap and some work good with eyes that don't see as well as they used to.

i use these air bags on my truck.
I don't use an air gauge.
I use the measure from the ground to the bottom of the fender lip on each side.

The gauge only needs to be accurate enough to avoid overinflation (right in the normal operating range for passenger car tire gauges), and to reproduce the setting that the user has found works in previous uses (I used about 20 psi). The 5 psi minimum isn't a precise thing - just keep some air in them so they don't flop around.

I have Coil-Rite bags. It appears that their maximum inflation pressure may have changed in the last decade. One should of course read the instructions for your own equipment, but 30 psi is close enough to get a suitable gauge - you're just not looking for one psi gauge or a hundred psi gauge.

I have installed these on both my Rams, the first one I used 2 valves, the second time a "T" with one valve. The part about using 2 valves will prevent losing both sides does not make sense to me as if I lose one side I would want the other side to drop also. Having air on one side only could create a dangerous towing scenario so I want both bags to be either "on" or "off", not 1/2 off. Just my opinion.
I use a short pressure gauge seen here https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

Funny how we see the same thing differently.
I like the two fill hoses because my truck had a slight lean to one side when the camper was put in. And I could compensate for that. I see trucks with small leans all the time. Guess I'm picky.
I also imagined that in a maneuver that shifted the weight to one side, the connected bags could push air from the heavy high pressure side to the light side and add to the tilt.
Anyways, your mileage may vary.

I'll have to check gauge on my bike pump as that is probably what will be used to fill these. Thanks for everyone's help. Julie

The pressure would equalize within the whole system, would not be higher in 1 side unless a check where installed between the 2 bags. If it was crooked to start and you add weight it'll be lower but still crooked. 2 fill valves the way to go to keep things level.

Did the Sumo suspension make the suspension feel harsher when driving unloaded? Thanks

We put the blue sumo springs in our 2917 Tacoma and they did not make it feel harsher. The Sumo springs come in different weight carrying capacities (are color coded) and the black ones may cause harshness. The blue version made the suspension feel firmer, but not harsh at all.

I also put the blue Sumo Springs on my 2010 F 150 and noticed a difference immediately. The SUMO Springs almost touch the axle, maybe 1/8" above it and on any bump will provide support even when the truck is unloaded. It isn't harsh though. The truck settles into them when I lower the Anderson (fifth wheel) Hitch onto the bed and it drops about an inch and a half or so. I'm very happy with the SUMO Springs and my belief, for a truck, is that the air shocks are unnecessarily complicated.

I also added the blue Sumo Springs to a Tacoma and found that like your tuck, the spring was close to or touching the frame while parked. I did have a camper shell on the back, so I'm guessing the extra camper weight caused the closeness. After instillation, I immediately noticed a bounce I hadn't experienced before. Because of the small space between the frame and spring, it seemed to bounce more. In an effort to reduce the bounce and allow the truck springs to work as intended, I cut the top rib of the Sumo Spring off. This alleviated the bounce, but still provided the extra support when towing or hauling heavy loads in the bed. I'm not sure if I messed-up the spring, but it seemed to eliminate the bounce while decreasing sag when towing.

Thanks for the info. I’m not crazy about adding a “bounce”. I use my Tacoma off road a lot when not towing a trailer and love the current TRD Bilstine suspension. I don’t want to mess that up.

I installed Sumo springs and replaced the Bilstiens at the same time on my 2002 Tundra. The gap between the frame and the top Sumo is about 5/8 " Close. I did not notice any bounce when unloaded, but I drive very tame when off road, just trying to get there. When hooking up my 21' the drop is very little, I measured but can't remember. It starts a little high and ends a little low, just right. After 2 years I'm very happy with Sumo's. With all the options out there I have no buyers remorse.

Update. The coil rite air bags are working as promised. Much smoother ride while towing.
