OBO A.R.E contractors utility topper in Lakeview, MI

I have a A.R.E Aluminum Utility/Contractors Topper cap in very good condition. It is heavy duty with factory sound deadened roof. Two tool boxes on the left side and one tool box and a side entry to the truck box on the right side. regular lift gate with glass on the back so you can keep your tailgate. all doors work great and lock (I have the keys). It is also wired with lighting and switches on the doors. It was on my 2002 (old style) Dodge 2500 short box when I got it and I have no use for it. it measures 69.5 inches across the front and 81 inches long. I do not have topper clamps for it as it bolted to the box on my truck. Asking $600 OBO.I could not beleive how much these cost new. May consider partial or trade for the right long range hunting tools (.300/.338winmag)
