I've been reading the posts on rangers/explorers, broncos, and toyota 4x4s. I'm looking at doing a 4x4 and am trying to decide what the best platform would be so feel free to suggest other vehicles. It will have to be a crew cab or Suv. It will not be a daily driver but must be streetable. It will be used for prerunning, backcountry trips, and general 4 wheeling. From what I've learned so far, the Ford I-beam has a lot of development behind it and seems to be a very strong design. I'm a little partial to Toyotas but the A-arm design appears to be inherently weaker than the I-beam but I would think it offers better handling than the I-beams with their radical camber changes through the travel. Also, what do you gain by moving away from leaf springs in the rear and is this feasible for a streetable vehicle that must also have usable passenger and storage space behind the driver seat?
