I noticed a post in the swap meet section. As it looked like it belonged here, I reposted it. It is the author's (rollis20) 3rd post and figured he needed a break... this time.

I purchased my GMC motorhome in California and drove it to Louisiana. Both air bags were dry rotted and one blew out as the motorhome sat in my drive way in Louisiana. My wife and I were really thankful that we got home safely.
I had time to research all options and settled on the SullyBuilt brackets with the firestone airbags. The brackets were ordered from Seattle Collision Center and the airbags from the Airspring Store on ebay.
The brackets are built very sturdy and easy to install. The airbags are also more sturdy than the original. Todd at the Collision Center provides you with all the information for the airbags as well.
By late afternoon Friday I had everything needed and had already removed my old ones. So I began the installation. It was not long I had everything ready for a test drive. The new system required a lot less air to set the motorhome in the travel level position. That means that the ride is softer with less wear on the bags. The cost was much less than the original if they were available or any other offering for that matter.
What is beautiful about it is that if you ever figure a way to ruin one of your bags, the cost will only the price of the airbag, which this one is very reasonable. For a few bucks you will be back on the road again. They are reasonable enough to have a spare one.
I like the system and thought that I should share the information.

I will agree, I too have installed the Sully bag design, only I made my own
brakets and baught the air bags on E-bay from
Airsprings (no shipping charges) at $118. The installation was very easy.

I've looked on ebay and the airspring site, and can't find specifics (part #'s) on the sully built bags. These sound like a good replacement. Would any one have the specs on building the brackets. Sorry if all this was once posted and I missed it.
I had considered the quad bag set up, but have heard it rides quite stiff and rough. And then there is the cost.
Any opinions from quad bag owners would be appreciated.
Thanks.
I found what I need on the sully bags, Thanks.
Still like to hear about the quads.

Dan,
Did you replace the shock absorbers when you installed the Quadrabag system? Some of the improvements you list such as the bouncing and wagging are typical of failed shocks(the bouncing especially)

I saw where Chris posted something like that the other day. I do not understand how he came up with that conclusion but he is entitled to express his opinion.
We have had the Quadrabag since 07. I love it. The ride, on our's, is perfect. I had almost new original bags on the GMC when we went to the Q. bag. I did it for safety reasons but have been quite impressed with the ride. My original bags were bouncy. I did not like that. The Q. bag is more firm so the the back of coach does not bounce like a ball when I cros railroad tracks and the like. With the Q. bag the side to side swaying of the tail wagging the head has stopped. Overall the ride and driveablity has improved a lot. We have about 35,000 miles on the Q. bag. I would never consider going back to a single bag system. Now, if we were "weekenders" maybe I would not have gone to the expense. Glad we did it. Would do it again.
Dan

I think the main difference between systems is one relies on the design of a single bag to both carry the load AND provide the rigidity necessary to keep the bag between the bogie arms. The dual bag (Q-bag, 4 bag) system employs additional structure to keep the bags in place. Hensley split the baby so to speak and relied on the bag and compression alone to hold the bag (that I think was deigned for vertical application)in place.
I looked at the dual bag setups and thought the additional structure added unnecessary complexity and the possibility that the design goal of easy welding-free assembly might compromise the strength necessary (but not being an engineer, that's merely eyeball speculation).

I suspect all these concepts have different spring rates with different resultant ride and roll rates. The amount of air pressure required to hold them up is a tip-off. Without making any judgements on which is better, the subjective handling will be different. Even then, it may boil down to personal preference.

The rough ride is a characteristic of the Harrison system as it
operates on 100-110 psi pressure, Ken Rose experimented with location
and bag size to where the Q Bag operates on 80-85psi pressure.
I have not had any women complain about our ride.
Once you drive it for couple thousand miles, you'll realize why Jim
Bounds pushes them so hard.
