Indeed looks great!
A few details to consider:
The road had tracked vehicle imprints, the 6x6 truck and trailer would leave a mark in the soil / gravel.
Always like to see a person or two, some contests 'bump' models with figures to vignettes or dioramas. If this is the case and you do not wish to compete other than for the vehicle then understandable leaving out personnel.
The 6x6 seems bare without stowed gear! The AM is always full of jerry cans, fuel drums, ammo crates etc a simple tarp over 'crates' would suggest stowed gear without breaking the bank on resin goodies.
