I would highly suggest not to run it as a single input. There is no roll stability. I have air ride on my wagon, having side to side division is pretty important.
If you air up the bags to raise the bed 2", everytime you turn you bed will roll 2" to the outside of that turn very easily. That's 4" difference from side to side.
Just a suggestion. Put both air valves in the fuel door. Very easy to fill from one location. Get a little dial gauge type pressure gauge. Look for the ones that show the pressure even after you pull it off. They have an air release button. You can use this to deflate the bags slow and precisely.
I just air up both, then bleed each to 50 psi. Takes 10 sec tops. Good luck.

I wasn't talking about a leak, but a shifting of pressures between both bags, ie, weight shifts from the left bag to the right, wouldn't the right bag deflate more and the left inflate more? See CHV_FRK's post above.

I have run 'em both ways, and the individual valve for each side is much better. With a "T", and both lines connected to one valve, I could feel the tendency of the unit to lean in a curve. I mounted my valves in the rear bumper, in the inset for the license plate. Never had a problem with anyone "messing" with them. As for fittings, you can actually use a standard brass compression fitting from the hardware store, just make sure you carry a small piece of the plastic air line with you to get the correct size. (I think it is 1/4", but get the size where the compression ring just slips over the tube). And VERY important, there is a brass ferrule insert you will need to insert in the end of the tube. You will have to purchase this separate, and is available in the miscellaneous type hardware. A good hardware person will know what I am referring to. I have used these on mine since day one, and never had a problem with them. You can get the fittings in tees, angles, or straights.

I get it,,, I am a little slow these days, I have had them on one line for 2 years now with no problems ( so far ) that does not make it right??????
Since we are on the subject, unless you are running in a circle,how would it be benificial to keep one inflated higher??? I am just asking, depending on results, I still have my second input, i will go back to indivudial fills
I have the bags tied together. Unless a person has an unbalanced load, the air pressure should be equalized anyway in order to have the suspension even, side-to-side. When I am loaded, the pressure I have in the bags brings the rear of the truck to the same level as when it is unloaded without any air. When turning corners, the truck's suspension prevents any rolling that would not be there anyway. Works quite well for me.
However, when uneven loads or a very high center of gravity are present, such as found with a truck camper in the bed, individual bags not tied together would make sense.
Yes, that makes sence,, I was told by the mfg. that they reccomend using 2 fillers for the reason of if someone would load up the back of the bed un-evenly, they could inflate 1 side more that the other to bring that side up to level...
