@ScoutingDad - My understanding is the MTH Premier 48' containers are High-Cubes. Compare this to Atlas 40' Containers which are not high cube (at least to my knowledge). I made a mistake in starting the Gunderson Maxi-III CAD build first. I should have done the Thrall 40' rebuild to start with. They look very nice with 40' containers regardless of height status. I have two of them in HO scale (10 cars total) and am thinking of buying another. I also have 5 of the K-Line Thrall 40's which I plan to make ends for when I do the CAD build-out. The containers they come with are not high cubes and are slightly undersized height wise compared to the Atlas 40'. However, the size difference does not affect the aesthetics...at least in my opinion.
