Only if you can hold your breath!

My tire gauge says 120 lbs

Yes go by the arrow. Our 36ckts takes 100 psi to get it on the point of the arrow.

Does adding a TrailAir pin box change the height of your camper?

I asked that also, and never got a response...needed a measurement from bed to pin plate with plate level

[spock123]

I called the factory and they said it might change the height three or four inches. I'll have to hook up camper and check the height on the road. I wonder what would happen you let the air out of the bladder, at least temporarily

I run around 40 lbs of air in my TrailAir, 60 lbs is way to much. it is solid with 60lbs

The TrailAir is adjustable like any other pin box.

Would pin weight affect the air in bladder? When do you air up the bladder, when hooked up or not hooked up

Yes , also air temperature plus elevation will also affect the amount of air required to level the shock cover. I always fill the air bladder when I hook up and on level surface. I do not check the air pressure at all, I rely on the line that the arrows point too. When the shock cover is even with this line, then I stop putting air in the bladder. I carry a portable air tank that I use to inflate the air bladder. I fill this from my compressor as needed. I have even let air out depending on elevation, I check the air bladder daily if we are hooked up and towing when we start out first thing in the morning.

Then I might have something wrong. I fill the air bladder with 120lbs of air the arrows do not move. When not hooked up its above the top of the arrows and when hooked up with 120 lbs you can't see the top of arrows

It looks like you have a pretty heavy pin weight. I put 100 psi in ours and the 36CKTS pin weight brings it right down to the arrow points. You need more air pressure to bring it up to the arrow tips with the weight on it but you might want to check with the manufacturer before you put more than 120 psi in it . That sounds like a lot of pressure on the air bag.

I plan to leave Topeka IN on Friday, take two weeks to get home. I'll keep the pressure in the bladder at 100 lbs until I get home. I'll move some weight then, I can't move much, about 500 lbs. I'll fill up my fresh water tank, that should take a little off my pin

You might be over the maximum allowable pressure. Mu hitch weight is just under 3,000 lbs and I never have to go over 90 lbs to get to where I can see the arrows. I suggest you call TrailAir (now a diversion of Lippert) for assistance.

Have you verified that your air pressure gauge is reading correctly?

[Telstar]

Make sure your on level ground with landing legs off the ground.

80 to 90 psi for SilverbackMel with 33rl; loaded; no washer or dryer. Use the arrow tips; beautiful ride!

My rig tows LEVEL. I adjusted my HITCH HEIGHT when I got the Silverback. My previous, 2012 5er was a Keystone, 36 ft; triple slide as well. ( same HITCH) however it was a STANDARD PIN BOX vs TrailAir.

I tow with a 2500 Ram; quad cab, 6.7 Turbo; short bed; WITH ADDED SPRING HELPERS. Looks and tows absolutely SUPER!!

[spock123]

I was told start at 100 lbs and then go lower. I'll drop the pressure down to 90 lbs. I have a digital pressure gauge that trust. I have a washer/dryer and a extra bank of batteries. Oh well I'll check everything out on the way home. Once I get to a level pull off I have to check the height of my camper, I was at 13 ft, I hope I'm still at that height

Our pin weight is also heavy. 2017 38EL. I add air per instructions but also adjust according to the ride quality. I keep about 100# in the bladder, don't get to the arrow, but ride is excellent.

Don't know what our psi is. Ours is still set as from the factory, even with a washer/dryer installed. Our full tank of water might even that out of the pin.

But one thing I do know....I LOVE this thing!!! Had the Roto Flex on the other 5er we had and it was ok running straight, flat and medium load. Curvy, bumpy and going up and down were not all that great.

Having moved from a motorhome to a fifth wheel with this Roto Flex, I thought that was just the way it was and endured a lot of chucking and flexing in the truck.

Not anymore.
