PSI in sunseeker 2860DS air springs

We are just starting with our 2013 Sunseeker 2860DS. Can anyone suggest the PSI I should put into our air springs?

The operating instructions list a number of configurations, I'm not sure which I have. But it looks like the range is generally 5-100.

Thank you for helping us.

We have a Sunseeker 2300 on a ford E350 chassis, I seem to get good results with 65lbs in the airbags.

I 'm running about 55 psi in mine (2300 Chevy chassis). I adjusted by about 5 psi each trip until I liked the ride.

On my 2013 Forester #3051S, I have 70psi in the rear air springs. My coach is pretty much loaded, meaning only a few hundred pounds from the GVWR of 14,500. My suggestion is 60-70psi when loaded and traveling. This gives you more clearance on your stabilizer jacks if equipped too. If you carry less water and cargo then 50-60psi should be fine.

I run 50-60 on longer loaded trips, 30 or so on around the house trips. The lower pressure is smoother, but like mentioned the 60 will give you a shade more rear jack clearance. The trip we're on now, I'm experimenting a little. Used the bags to level the coach side to side in the shop before departure. I can't rearrange enough stuff side to side to level it out, and the MH is heavier on the passenger side from the factory, so figured I'd try it with the bags. Seems to ride about the same, although I have 30 in one side and 55-60 or so in the other.

We just completed our 2nd trip after installing the ride rite bags on our 2011 3170 50 psi first trip 60 psi second trip . i think i am going to stay at 60psi . either way it is 100% better than no bags.

They must have started using softer leaf springs on the rear axles. On our 06 I haul a 16' enclosed trailer with 700 pounds of tongue weight and I would never run more then 60 psi. At 60 the trailer doesn't even make the RV squat a 1/4". If I ran 90 our teeth would fall out.

I had 50 pounds in each on my trip to Florida in March. Going down I-95, especially in South Carolina, the unit seemingly continually "banged" going on the segmented roadway as it's constructed in S.C. I didn't do it until I got home, but I reduced the bags down to 10 pounds, I don't get the banging as I did before. Not sure the bags are doing much for me.

The rear Air Springs improve vehicle handling. I would not reduce the pressure to 10 psi. There are warnings to keep them inflated and a very low air pressure could damage the both bags.

According to Firestone, you can operate them from no less than 5psi to no more than 100. But that is simply on paper. So take it with a grain of salt.

Thanks for the replies, I will shoot for 50-60 for out next trip.

How often do you check the pressure during a trip?

If they are new I would check them in a day or 2 to make sure there are no leaks. After I established mine didn't leak I go 2 weeks to a month without checking them and they are about 3 pounds lower then were I had them.

I run mine at 70. But there's not much air in them. So temp swings seem to cause them to lose a bit. So mine were down from 70 to 55 after about a month.

I pump mine up to 80 them let a bit of air out with the tire gauge to get them exactly at 70. Just a little bit of air release and you lose 10 lbs.

This is a good point!!!!!
They are not large bags! So when you go to fill them do not hold the air on it like your filling a tire. Little burst is all you need!

Do you travel with a small portable compressor?

Seems that would be handy.

I carry a Portal Cable roofing compressor. It has a very quick recovery and has a 130 psi output so it's very capable of doing tires quickly also. I put it in my larger rear storage compartment then basically made a extension cord out of Romex wire that I pipe over to my outlet which was in a smaller compartment up front. This way I just have to fire up the generator and turn on the compressor without having to take it out of the RV.

At first I had 60psi on the driver side and 26psi on the passenger side. I could not get the gauge on the stem so I assumed it was 60psi from the factory the first couple trips When about the third trip it seemed the MH would sway more that it should in the wind and when trucks blow by you. So I removed the stem cap and the 2 washers and pulled the stem out as far as I could and checked the psi. That's when I discovered the 26psi. I filled to 60psi and this last weeks trip was a 100% improvement in GP driving and in the winds. Since can't get the stem out any further I will have to do the stem & washer removal trick to measure the psi and to fill. I think the stem is sealed with some filler or caulk.
