Trail air hitch
How many lbs of air pressure do you use in the bladder of the hitch when towing.

depends on which rv and how much tongue weight you have 
each of us have found a comfortable setting through trial and error...
A trend I've seen is that most of us run LESS than what would be in there if we aired up to what the arrow decal calls for...
ours was just too hard when set according to their suggestion and all the shock was transferred to the truck...
you don't want it too soft or too hard for your load... which could change (a bit) each tow depending on how many shoes the wife loads 
start with it connected and aired up to about 1/2 inch below the arrow tips -- iirc, that was about 60 psi for me ??? but again, depends on your tongue weight and the push/pull of your setup....
i.e. have found after I pull a bit, it may need adjusting because I aired it up when not connected or not in the 'normal' towing position....
Sorry, that's not a definitive answer, but it is correct

Sort of a trial and error. Well depend on the TV setup and how much weight is on the pin. We've heavy in the pin with a stock suspension dually so I run 85 to 90 Lbs, but other run much less.

Does anyone know the rating of the actual bag? You should be around 50% +/- of that number, and then fine tune for your specific ride.

I believe the bags are rated for 100psi

Dave is right, I spoke to them and they said max 100 psi, but if you put that much - whew it will be a rock --- I just measured mine and it's @ 55 psi and rides about 1/2 inch below arrow tips...

Our Dealer had our maxed out and I didn't even notice for a couple of days - it rode high and terrible. Finally looked out the mirror and it dawned on me I need to adjust it down to the arrow. Too many things spinning through my head at the time.

Has anyone had any problems with the air pressure reducing over time when the rig is parked and not being used?

Yep. Always recheck and add air after sitting long term (2 to 6 months). Doesn't need alot, but some to bring it back up to the pressure we tow at.

This is just one of the many checks we should be doing on our RW's. I check mine each time I am hooked up along with my tire pressure.

Yep........ it's just like a tire that sits over a period of time.....will lose air pressure & must be aired up otherwise you risk having the front of the 5er making contact with your truck rails while pulling on uneven terrain.

Yes! so much in fact it's annoying. It isn't just air pressure, but load changes (water) and maybe even impact from altitude changes. Sometimes its overinflated, such as the ride home when I run without water or gear.
My fix is another remote controlled air compressor like I have for the truck air bags. I've already installed the compressor up in the pinbox cavity, I just need to wire it and install the remote hardware so I can just look in the rear view mirror and adjust the ride to the arrow as things change.

THAT's a great idea.... Love the wirelessONE on the bags, but every once in a while while going down the road, it thinks it needs more air in the bags and we feel like we are in a massaging bed
wonder if you'd need to wire in an off switch for the hitches compressor so the compressor does not come on during a particularly restful night - that BBBBBRRRRRAAAAAAAAPPPPPP would wake up the dead

Yep, the plan is to add a switch next to the one for the dock lights under the nose. I found a two gang switch plate and matching switch.
It is funny you said that, we took the "Clydesdale" out to play yesterday and when leaving the restaurant I hit the key and "bbbbrappppp"! It caught her a little off guard and I noticed those big eyes of concern

AA, that's a great idea. Love hearing about how you have re-engineered your RL. I can't keep up...
