TrailAir question.
The dealer where I purchased the RV said to inflate with no more than 65 PSI. That will not get the pin box loaded to the inflate to mark. I have found about 90PSI works great to get it where it needs to be and have had no issues. I assume everyone else does the same thing as none of the documentation has any limits mentioned, just inflate to the mark with it being level and loaded?
Second question is I need to add air as after about 3 days it’s back down to 60 PSI. Literature says adding after time is normal but this seems a little quick?
Thanks

Mine took 105# with my Superduty. 90# with my RAM.
Yes, they leak down. I have not found a leak and have replaced the valve stem twice.

Compressed air is warm, as it cools the pressure will degrease slightly, just like your tires. That's we carry compressors.

Yes mine leaks down rather quickly as well. Have tightened everything and re doped all threaded parts. Don’t worry about the pressure what ever psi works to level out to arrow on shock is ok.

If I had to do it over I would probably get the MorRide. You don’t have to use air. All my curtains in my Cedar Creek dropped on the trip last year to Alaska. I really can’t tell the difference in the TrailAir and the standard pin box. I can see the pin moving but really no difference it seems to me

Thanks everyone, seems it works more or less the same for all of us. I had a MorRide prior to this and will say it’s a “slight “ improvement over that. Not as much of an improvement I was expecting from a Airbag pin box I think. But hey, it is a bit better so it’s all good.

No difference from standard pin box? WOW! You have a problem! Something is drastically wrong!
I towed a 37 ft Keystone x country 4 years ago and it had a standard set up. Trip from HELL!! Trail Air, now similar weight and size Cedar Creek, all up and down east coast; no chucking, nothing moves inside. Cannot feel RV at 70mph. Takes 85 pounds of air on mine to hit the mark. My truck and RV are perfectly LEVEL for towing. That could be an issue for some if unit is not. Try pulling a little red wagon with 2 kids sitting way back! Almost same rear force and front sway.
I did add “lift” springs to my Dodge to hit the level I was seeking.

I really can’t tell the difference in the standard pin box or the TrailAir. Curtains fell with the standard pin box and with the TrailAir. Things move around in the camper with both pin boxes.

The 5th is going to bounce and kick as it rides on its own suspension. The TrailAir will "buffet" some of that energy from the plate in our trucks which will help with the up and down chucking via the air bag however the forward/backward chucking is not insulated by the up/down air bag insulation. The MorRide deals with the forward/back chucking with the controlled slide that is built into it. We just need someone to produce a MorRide/TrailAir pin box and that should address all of the chucking. Sounds simple right? Maybe call it the "EasyRider" with a icon of a hippy on a Harley with long forks and high handle grips wearing a bandanna. Cheers

Or maybe call the Easter Bunny. For the life of me I can’t tell the difference, no one rides in the back of my fifth wheel. I have a B&W hitch and it seems to help. I hardly ever put air in my tires but it seems like everyday I’m pulling air in the TrailAir, it’s about every time I move the camper I have to climb in the truck. Should I trade campers again I’ll not install a TrailAir. Mine didn’t cost a whole lot but it just doesn’t work like I thought it would

I run about 110# with my 38el, only have to add air every four months or so. Makes a big difference when towing.

I honestly can’t tell the difference. I guess some can

For those that arn't adverse to replacing your Hitch, Here's a great combination to eliminate chucking and bounce. The MoreRyde Pin Box and Comfort Ride 245 hitch. The hitch does not use air bags so there is no air pressure to maintain but the hitch absorbs all the down force from the pin box via the energy cells and it works. I researched hitches to death for the better part of 2 years, I have the 245 hitch but no MoreRyde pin box on my current trailer. We use a Sidewinder pin box due to my short bed 3500 but the benefit of the Comfort Ride hitch is very noticeable even without the MoreRyde pin box. I have no affiliation with Comfort Ride, just a customer.

How your weight is distributed in your RV is going to make a huuuge difference. Our front BR has no washer/dryer.
We feel and see a tremendous improvement with TrailAir. No chucking and nothing bounces around in cabinets......
Smooth ride!!✔️

Our washer/dryer is downstairs. It could be the tires, I have G614 Goodyear tires inflated to 110lbs. Maybe the tires bounce to much as all our curtains fell

110 PSI may be too high.
For example, if you have roughly 12,000# on the RV axles...or about 3,000# on each tire, the tire load chart may very well call for less pressure.

Sounds like you need shocks on the trailer. For curtains to be falling it has too much bounce in the springs. TrailAir pinbox cushions the bounce between the truck and trailer so it won't help much for bouncy leaf springs. But shocks will by dampening the bounce.
