Well as for the climate I travel all over the country and hopefully soon countries. I have a 2012 Nissan Frontier King Cab that has a lot of extra weight. I'm looking at a heavier load rating. I have a RTT, camper shell, soon to be drawer system with fridge integration, and soon to be armor. I've had the KM2 and AT from BF goodridge on my Jeep. The AT's suck in mud, and since I have no idea what the road will have in store for me I'm trying to stay away from those. I've liked the KM2's but as said in a previous post they don't like wet roads. Currently I'm leaning to the KM2's but I'm looking at Cooper more due to your previous postings.
