Contributor | Advice request - I'm looking at the Ops Manual jack points and trying to translate that into practical choices. I heard the advice about not using the torsion bar, but what about the terminus point where each end of the torsion bar is anchored to the frame? It seems reasonable since those points are where the load is transferred to the drive wheels going down the road. I saw Len's effort at correcting sag in the body work, and I'm leery of doing anything that will rack or twist the frame. Thanks for any advice or pictures of ideal jack and support points! Best, - Rich | ||

You should also support it at the rear ends of the frame rails as well since the frame will then also be carrying all the normally unsprung weigh of rear hubs/tires. | ||

Regular Location: Greensboro, NC | Hey Len very nice work on your coach GREEN with envy, in your pics the stands that you used to support the rear of your coach did you custom make those or did you purchase them somewhere? #721 was formally owned by Joe Knight and has rear air ride which is one of the winter projects because the system leaks down, air tank is to small, and since it has an 8.2 Detroit I would like to get a engine driven compressor to keep up with air demand. | ||

Elite Veteran Location: Oceanside, CA | I bought them then made a small attachment to bolt to the bumper mount attachment points. http://www.homedepot.com/p/Tiger-Brand-Super-S-Series-36-in-Jack-Po... I use the Duramax's factory Sanden a/c compressor to run my air system, it takes less than 30 seconds to get the system to 150psi. You don't need much of a tank, I think mine is maybe 3gal. | ||

Regular Location: Greensboro, NC | Well since I have a Detroit N/A I am stuck trying to find a air compressor for it has a vacuum pump already mounted on it for the cruise control and I am assuming for the brake boosters also. | ||

Expert Location: Cottage Grove, OR | While do not presently have air ride, if I did I would focus on eliminate all air leaks before I would change air supply system. Without any air leaks you may very well be satisfied with the present system. | ||

Regular Location: Greensboro, NC | Yea going to work on that just not sure if the pump is up for the task, and I need a new tank the one that was on the coach looks like Swiss cheese Joe Knight did some good up grades to #471 but it has sat for so long I am going to have to redo the most of the inside including the floor rotten and no insulation. | ||

Elite Veteran Location: Oceanside, CA | Viair and Airlift both make good medium duty 12volt compressors. Air suspension is a huge market, lots of hardware options to choose from. I'd probably run an electric vacuum pump as well and get every bit of load off that 8.2 as I could so that I could run a much larger cooling fan without taking so much of a hit on power.. | ||
