Took me about 4hrs all together, most of the time was spent removing bumper and splash guard. Broke 4 of those stupid little clips. Cooler is rated at 13000 btu which should be good for about 18000 gvwr not really sure how they get that number but ok. Was able to use two existing condenser bolts to mount the brakets and then one sheet metal screw for the third braket. Did not use any of the zip tie things it comes with they just dont seem sturdy enough. I am very happy with the install and the cooler itself, good cooling and Low Pressure Drop. Pulling a 24' pontoon boat with 85hp johnson outboard to Watauga lake tomorrow. All together I think the boat plus trailler ways around 2800lbs. Will update post with the results.
