Trailer suspension air pressure gauge.

As an option you could use remote pressure sensor from eBay and set it up in dashboard somewhere

 

I have a PressurePro tire monitoring system on a travel trailer. Wireless pressure sensors are screwed into the tires' Schrader valves and send each tire's air pressure for instant readout in the cabin via a monitor. The system alarms if it goes too much out of the spec you want. Such systems are fairly cheap and effective.

 

I plumbed pressure gauges into all my air ride trucks and trailers. It is the most awesome thing.

After some confirmations, 60 PSI on all my vehicles means that the tandems are at 34,000 gross. Every extra PSI is 500 lbs of extra weight.

I can finally load my trucks to full capacity without running illegal. Was recently stopped at a truck scale and let go after the lady double checked. Great experience.

 

You could have drivers mark down the psi on full loads for each trailer. I'd make sure to have them send a scale ticket and picture of the gauge to one person for verification.

It would bug me to have that available but still need to pay for a scale.

 

We've just about traded out all of the "digital weigh" system trailers. Everything since are simple pressure gauges. We know when we're safe, and we know when we're marginal and better weigh.

80 psi on our trailers and 63 psi on our tractors is very near 34k

 

We load our tankers with a simple 100# air gauge directly mounted to the trailer tandem air bag. Pretty easy to get within 1000 lbs. of our 78,000 target every time.

 

Mine is the same. A few pounds over 60 on my drives and 80 psi on the trailer. Pretty handy little trick to know.

 

We have suspension gauges on top of our tankers. When we load lime, we're on top of the trailer. Makes it really easy to load to 79500.

One thing we have found is the smaller the line going to the gauge, the slower it will react. We can load 55,000 lbs in the trailer in about five minutes. When it's cold, the gauge reacts slower. So you think your weight is light, add some more, and then your're overloaded. We run 3/8" lines to the gauges now, with no issues

 

I do have one on my kenworth t680 and thst susp load gage only tell you about the drive axels. However be careful because when it is 60 psi your steering may be overweight!
