Trailair pinbox pressure

[GaryO]

Dealer is installing a trailair pinbox on my new 36ckts today.How much air pressure are most of you using for best ride? Will this pinbox raise the height of trailer?

[dieselguy]

I have a Fifth Airborne pinbox which is similar to yours. I run 95psi in mine on a fiver with a similar pin weight. The pinbox and hitch in the bed of your truck are both adjustable. If you're lucky and get a tech that knows what he is doing, he will measure your old pinbox height before he removes it and try to match the Trailair to that measurement as close as possible.

The pressure will very depending on the actual pin weight. Set it according to the arrows on the shock for proper set up.

Generally with 2015 Silverback 36ft, no front end washer dryer, my LOADED FRONT BEDROOM AND CLOSET it comes to the arrow at 80psi. Could be slightly more on yours, according to load.

These tires do lose slight pressure over time so you might want to put it on your check list. Mine "looked good" after sitting 3 months but once hitched, not so good! Don't be deceived by just looking. Check the hooked up position.

I live by I phone. There is a very good checklist out there at the Apple Store for free: RV Checklist. Easily add and delete to fit your personal RV needs. I would bet there are others or perhaps
non I phone apps for this one.

Learn all you can about your new RV. It's been a year and I am still learning every day. And, we had a Keystone fifth wheel, same size for 3 years. So not our first rodeo 😀. We changed floorplan needs otherwise we would still be at Keystone. Could not get the deal done on a Montana High Country!

Safe travels

X2. Actual pressure is irrelevant. As for height, my 36CKTS with a penguin bedroom AC was 13' 4". However, you should measure your unit on level ground while hooked to your TV. A 2x4x8, carpenters level, a 15'+ tape measure, a 12'+ ladder and a helper to ground the tape is all you need. Enjoy your travels.

I installed my first Trailerair pin box on a 318SAB Cougar and I than ordered one with my new Cedar Creek 34RL from the factory. I will not tow without one; this improves your ride so much when towing and is less stressful on you and your passenger.

Now I have notice that you will need to air up and down when every you hook-up and or change elevation when towing in the mountains and or descending from them + temperature changes. I carry a 125PSI portable 11 gallon air tank in the back of the bed of the truck for this purpose. I just inflate the Trailair bag until the top of the shock aligns with the arrows on the bottom. I have never measured the air pressure in the bag since I have the alignment points on the shock.

I agree. I never use a gauge when setting my pressure. I adjust it to just below the top of the arrow which works well for me. The amount of air that is required will vary according to how your trailer is loaded. Too much air can make it ride nose high and will cancel some of the smooth ride. After you use it for awhile you will see what I mean. It's easy to see with your inside rear view mirror and you can determine by the amount of movement about where you want it. I just use a 12 volt compressor to adjust mine.

Looks like i'll be shopping for a 12volt compressor.It will only be used for trailair pinbox and in emergency for tires, will be kept in 5th wheel, any recommendations?

[donniedu]

Forget those junk 12V compressors. They can take for ever to raise the trailer, if ever. Instead, go shopping and buy yourself a 150PSI pancake compressor. Bought one on sale at Lowes last year. Was so happy with it, I gave away my big compressor. Easy to carry and store, and as a bonus when fully pressurized will hold the pressure for a week or more.

There are a lot of different compressors on the market, just be sure it will handle your tires. This is what I have. It is a great unit but is a little pricey.

Not all are junk, however with your compressor if you need it along side the road you will need a inverter or generator.

I just use a cheap one. It works fine and I can adjust my air pressure in a few seconds. However, I do carry a spare just in case. I've never used it for my tires as I also carry a small 110 volt compressor that I can use when I'm parked somewhere. If you shop around you can find a adapter that will allow you to use the cigarette lighter type plug on the compressor and plug it into the 7 pin plug on the rear of the truck...Works very well for me. You could also use just a hand tire pump. The airbag on the hitch doesn't take much air.

I was to cheap to buy the 400P. I have the 300p and it works just fine for everything

[wanderer69]

If you are also going to be using it for tires also, you may want to consider one of the 110 volt 125 or 150 PSI tank type. The tire pressure on your new 36ckts is 110 PSI.

[B and B]

I have a Coleman compressor from 1972. It works just fine on 12 and will pump up to 100 psi if needed. Some just work forever,

[ependydad]

For the pin box, I find it is easiest to use a good quality bike pump.

For tires, I use a 3 gallon Porter Cable(?) pancake compressor - $100 from Home Depot.

Does anyone topoff their Trail-Air before connecting to the truck? The correct amount of air for mine is 94#.

I'm aware what the Trail-Air manual says about it.

[cfiowa]

Top it off till the arrows line up.

I service mine to 40 lbs before hooking it up. I added the gauge so I can easily air it unhooked

85 psi before I hook up
