stable lift installation- centering question

I have a 1968 Avion C11 that has the three lift jacks from the factory. There is one lift jack on the passenger side and two on the drivers. Can I assume that Avion centered the one jack on the passenger side for weight balance ? It's not as critical with the Stable Lift I don't believe but thought I would ask. I purchased a used stable lift that I'll be installing this summer and I'm planning ahead for where it has to be on the camper AND where I want it on the truck. Ideally I can mount this so I can have access for example to the fuel filler on the truck. I can call stable lift but thought I would start here. Thanks
  • Reddog1 yes I had already planned to make the internal sandwhich plates out of aluminim plate for the very reason you suggested. I know for a fact the passenger side I'll have to replace the plywood in the jack area because it has slightly collapsed. I may skip the factory sandwhich of wood/foam/wood and go strictly wood for the strength. The switches I think for now I'll use them but I can see where your modification has merit but for now they work so I'll use them. I do appreciate your feedback it is very helpful.
  • I do not consider myself to be an expert on the stable Lift by any standards. I did in fact install my Stable lift by myself with no help, years ago. The only mistake/redo I had was the plates inside the TC, used to sandwich the existing TC overhang with the Stable Lift outside plate. Initially, I used 1/2" plywood. Overtime, the mounting bolts wicked water to the plywood. This caused the plywood to fail with the carriage bolts. I replaced the 1/2" plywood with 1/4" aluminum, and have had no issues since.

    The plate inside the TC does not need to be one continuous piece, it can be several pieces.

    I did/do not like the three toggle switches provided by Stable Lift. They work great, but you cannot see what is happening on the opposite side of the TC. I made a wire remote for my lift. I can raise my lift from either side of my TC, and also have a connector inside the TC to raise or lower the lift.

    I do have as source for the gear box and motors. If I can be of help, let me know. I am sure you will appreciate your Stable Lift as much as I have mine. Mont, at Stable Lift, was very helpful with my install.

  • I do not have install directions the previous owner did not have them as the lift came on a dead camper he purchased. I don't want to over think this, as you point out the SL spreads out the load. I'll get it centered on the camper as best I can and also see where the cross over pipes are in relationship to the bottom of the truck. I've been on SL's website many times so I have a decent idea how it works/mounts. But it never hurts to get additional opinions. Thanks
  • Typically, the TC is mounted on the truck with the Center of Gravity (CG), balance point front to rear of the TC, at the center of the axle or 2 to 3 inches in front of the axle center. If you mount the Stable Lift single jack within that area it should have no problem.

    There are a couple of things to consider. The single jack will be lifting 50% of the TC weight. Depending on which jack was used on your lift, it probably is rated between 2,500 and 3,500 pounds. The lift has a hoop at the bottom, which spreads the TC weight over a pretty large area, including on uneven ground. Typically, the front hoop tubing that goes side to side are mounted directly below the original front jacks of a four jack systems. The rear hoop tubing typically ends up at the back bumper, and not at the rear of the TC. On my 11.5 foot TC, the rear hoop side to side tubing crosses at the rear bumper, which is about three feet from where my original jacks were mounted.

    The lift jacks opposite the single jack side are only supporting 1/2 the weight each as the single jack side. With this in mind, I can't see how it makes a difference function wise as to where they are located.

    Each TC is a little different and makes the lift a bit difficult for one size fits all.

    Do you have any instructions on how to install the lift?
