Did the research for 12 months or more, factory half height barrier is my choice. Just started fitout of rear space. Can be fitted behind front seats etc if required. Fits my Off Road or touring or expidition configuration options (as not all trips are the same).
Hope this assists in planning your trips and fitout.
The half height cargo barrier is lighter, and it will also supports a 105 amp hr Lithium battery (flat type) plus other like supporting a 100 ltr water bladder for extensive expedition trips. (This is clipped along the lower frame that easily supports the weight).
I believe the half height barrier is the most flexible choice. Even after the draw system is fitted with a 80 ltr fridge is in place. Still leaves options to remove rear seats replaced with a flat panel (same fixing) for even more storage options.
As always with any off road vehicle, its mandatory to consider weight (for all loads) keeping as low as possible, essential to.also minimise roof load.
Hope it helps.
