Shortening a 48" TorkLift Extension

I have and use a 32" extension though I thought I needed a 48" to clear the camper. I put a double over/under extension in it which brings it out to the edge of the camper, the top can be used for a bike and not for towing. Installed an extension in the lower with a step moves it out the needed distance. The step works well and can put a receiver in it if needed for towing.
