You keep your flats under tall parts of the steel? Why?? We keep them pushed underneath the lowest steel areas- the areas where the lowest steel "shelf" is like 8" from the ground, so the flat itself (the wooden part) is under the steel and we just have the handles sticking out.
I feel like I have to be reading your post wrong, otherwise it sounds like you guys are losing a TON of space by keeping your flats out all the time.
But yea- we're having the storage problem as well. We've been short on space for a while, so yes, let's add more vehicles that we TOTALLY don't need! Uboats are cool for new/boxes freight but my STL also seems to like them for loose stock and backstock...everything falls off. I don't understand lol
