Gotcha.
Ok, please elaborate on the crane's application. Lifting game?
The aluminum inset tracks are called Versatrack? Link to share?
The main use will be for game, but I am sure it will find many other different uses. Pretty nifty little unit, all aluminum so relatively lightweight. The top of the camper is way off the ground, and will see a multitude of uses from storage, sleeping, spotting, lunch breaks where you need to supply your own view, etc...so a crane and ladder will probably come in handy.

Little fittings slip into the rails allowing quick adjustments, with a fairly serious load rating.
