The distance on the stock hydraulic lift assist are 13" hole to hole when closed. The specs on your actuator say it is 18" retracted. How did you get it to fit?
There is an old post about this where a dealer was making these but they decided against it for liability reasons. So I took it into my own hands and here's some pictures. I still need to modify the plastic shield and the switch is temporary so I can get to picking up rocks in the field. I have a Mystic switch panel waiting to be installed.View attachment 45615View attachment 45617View attachment 45618View attachment 45619View attachment 45620
Tried several actuators and could not get any to fit my P1000-5. I'm thinking the underside of the P1000 bed is different than the P1000-5 due to the rear seats. After several attempts to get an actuator to fit/work I stumbled on a brain fart. Every time I removed the old bed lift assist tube I supported the bed in full dump position with my overhead hoist. After failing with the actuators I thought instead of pushing from the bottom up why not pull from the top down. Problem solved. P1000-5 power dump bed
Its a concentric #LACT12-1000B. I got it from surpluscenter.com for about $250, but I see its a little higher now. They are available all over the internet. It was the longest I could find to fit in between the frame and box. It does limit the full dump travel but it hasnt caused me a problem yet. The brackets are 2x2x1/4 angle iron.
Theyre never big enough. Started out 30x40x12 tall then, fil said make it big enough for the combine to be worked on, that turned into 40x60, then I said my toys are going to be in there too. So now its 60x64x20 tall. Insulated with in floor heat.
