ABSTRACT:
A combination is disclosed having a trailer, telescoping support members, and a drive. The drive has a motor and a drive shaft, and the drive shaft has a first end portion affixed to a first cross member and a second end portion affixed to a second cross member. The first cross member is operably connected to means for moving the support members between raised and lowered positions. To install the drive on a trailer with a cross member, a segment of the cross member is removed and both ends of the drive shaft are affixed to portions of the remaining cross member. A kit having a drive and a template may be provided for retrofitting trailers. The template is a sheet that may be positioned on a cross member to determine locations for cuts and holes.
