Be careful here. These tanks are actually 5 long as it says. That's almost 67' in n-scale! I built the kit and when I set it on my layout it just overwhelmed everything around it. There is a solution however. I just cut the tanks shorter! These will fit with almost anything when you consider you can cut them to fit. And the left over lengths? They make great vertical tanks! Very nice water-slide decals and enough material left over to use for other projects. Well worth getting if you're looking for some large/adjustable propane tanks.
