I'm running a full rack on my Monty, because I need the inside space free for family and dog.
I like the look and practicality of the full rack. If it's just one or two people on backcountry trips then there is really no need for a full rack.
Check out the two sizes BajaRack has under production.

'02 Montero: OME suspension, ARB front bumper, homemade skid plates & spare tire Blitz can mount, extended diff. breather, K&N air filter, Optima Yellow Top, BajaRack, IPF lights, Goodyear Duratrac 265/75/16's, RUD 4x4 Grip chains
