Trail Air Pin Box - needs air each trip

Pressurize to 100psi overnight. Spray a little soapy water on the valve stem.

The 100 psi works on the CenterPoint bags also.

I have a Trail Air up front and the centerpoint suspension out back, and onboard air for both. A little viair 90 compressor starts at $66 on Amazon, add 10-15 feet of 1/4 inch air brake tubing, a pair of fittings, and a power switch, fuse, and some wire and you can have onboard filling of the trail air.

I have to admit that I am in the crowd that DOES have to air up every few days. I also carry a small air compressor. I would say I can go a week at the most. Mine has been that way for several years. I've learned to live with it. Maybe I should try another route.

I have to top mine up after it sets a few weeks. I keep a cheap 12v compressor in my truck just for that.

Yup, that's a problem. Only have to top mine off once or twice a season.

Ya picked mine up before a trip to Daytona after being stored for 4 months. I never checked the air in the pin box and when I made a sharp turn to leave the storage area the electrical box hit my box on the truck. Put a nice dent in it. With air it just clears the side. I need to move box when I get it home

No you have a small leak.
Check the valve stem! Spray the air chamber.
If yours has two chambers check the connections on the tube between them.

Ok, you confirmed it. I need to check a tire for some air loss, too. So it looks like I have a soapy day in my future.
