If you get the Toyota, which would be a beast to drive on the highway, go ahead and get a trailer. If you're getting a trailer, go ahead and get one that can haul the Toyota and your Jeep. If you are doing that, go ahead and get a big ass heavy duty pickup to haul the trailer.
Help my memory...is Bane your first offroad vehicle (not including any 4 wheelers, SxS, or dirt bikes)? Does your wife have any experience with this hobby (eh hem...sport)?
