I just made a deal on a used 1996 volvo daycab with a m11 cummins. In the design and calculating phase now have been searching for slide out kits or plans and been to the liftco site but am not seeing options or prices has anyone designed and built one themselves? I been thinking how I could do it with rollers locking mech and hydraulic cylinders it is all easy in the planning phase but actually fitting it and making it all work together is a different story.
