Another factor that would influence my choice between the two options is whether the trip leader is driving a SWB vehicle. When you're driving a LWB vehicle and following a SWB lead, it's crucial to have the central differential open (4H for Pajero/4H auto for Wrangler). This setup reduces the turning radius, making it easier to follow the track created by the SWB lead.
I faced significant challenges when I drove the LWB Pathfinder, which lacked a central differential. In this vehicle, the front and rear wheels were locked at a 50:50 power distribution at all times when 4WD was engaged. I had to make the wheels spin excessively to stay on the path created by the SWB lead. In technical terrain and more advanced drives, deviating from the lead's track can be quite risky.
After driving the SWB Pajero, I've come to realize that driving a SWB vehicle in the desert is a blessing! especially vehicles like the SWB Pajero and JL, which allow the central differential to remain open when 4WD is engaged.
