G'day from Australia
I am another one who used to build models in my younger day and now I am semi-retired and needing a hobby I thought about building trucks.
2 reasons, firstly my son drives a Kenworth 909 for a soil delivery company in Melbourne and secondly model trucks (1/25 scale) don't take
up as much room as model planes. My models are relegated to my workshop/garage because according to my wife they do not go with the decor in our house.
I am sure we would all agree they would but "happy wife, happy life"
