Built this retired LEGO Creator set 31075 Outback Adventures set. Even it’s a simple kit, it has a very nice and detailed classic off-roader. I built all 3 models to compare each of them.
Open the box you'll see 3 bags: 2 bags are bricks and 1 bag of manual books.
Off-roader - This is the best model among the 3 and I like it most! The classic off-roader is detailed with a hood-mounted spare wheel that also operates the working winch, cab with roll cage, bull bar and wide rims with chunky tires. I like those chunky tires, they added extra points to the entire off-roader design. Besides, this build comes with a buildable tree trunk and a nice dog.
Wilderness Campsite - This build uses lesser bricks compare to the off-roader. It comes with shelter, dinghy and mountain stream. It is kinda minecraft terrain, unfortunately I’m not attracted.
Winch Helicopter - Even this build uses the least bricks, I prefer this compare the Wilderness Campsite. It’s simple but it has some nice design such as the engines, the winch etc.
Final thought: Among the 3 models the off-roader is the best. It has lots of playability and detailing compare to the other 2 designs. Even the winch helicopter is not bad, it's too simple. Personally I'm not attracted by the Wilderness Campsite.
