Yes, I like the 'covers' for the spares. Presumably you lay the tyres flat on them & then lift up the cover with the tyre on it when mounting the tyres?
The 'plate' at the top of the covers (when in upright position) looks like a handy spot for mounting some maxtrax.

Is the chassis extended on the Toyota? Looks like a lot of rear overhang with potential for a lot of weight behind the rear axle.

The undertray box built around the fuel filler is neat.
