Truck Forums - New member new ride

Hi all new to the forum and to wheelin, I'm hopeing you all can give me some advice. I just bought an 85 F250HD 4X4 and I'm wondering what kind of off roaders these make and if there are any known weaknesses, its got a 460 with a granny 4 speed dana50hd rear and dana50ttb in front. I know its gotta lot of power and is already about a foot and a half off the ground so I'm mostly curious about the tranny, t case, axels, and suspension rebuilding not lifting. All so I'm lookin for some good trails around Colorado Springs. Any help is greatly appreciated thanks for reading.
