hey goth,
i have the kilimanjaro 42x60 rack. i can tell you that it is solidly built and very sturdy. with my hilift, shovel, ipf 960's, cb antenna, 4 gallons of water and back up light up top my X doesnt really feel top heavy at all. you will notice that it leans alittle more but not to the point of being dangerous or the point of being higher risk of rollover. rust isnt a problem with this rack either.
