Some pix of the spare tire mount on my VX are here (last 8 pix):

This is pretty much a permanent modification since you will drill 2 holes through the tailgate - you won't be changing how you carry your spare for different applications.

It looks to me like you will be able to use the tiregate on the VX but you won't be able to open the rear door whilst it's mounted. It should be possible to fabricate a drop mount to lower your receiver for that application but you would definitely lose departure angle though.

I'm kinda visualizing a spider bracket spare tire carrier (custom to the VX) in my mind right now that just clamps to the rear door rather then bolting through. I might just hafta go visit welder guy today to see what's possible.

The other option is what Johnny is talkin 'bout - a bigger basket that will hold your spare & the coolers & junk.
