The basic structure went together very quickly but the windows were, well, not such a good fit. The windows in the basic body, were partially laser etched on the inside and had to be cut out with a knife. The windows had no trim, so the fit had to be perfect and it wasn't. I really didn't like to gaps, especially in the cupola, which had been laser cut all the way through- just a bad match up. So, I cut some small styrene strip, painted it and mounted it on each window. The process was slow but I think improved the overall look of the final product.
I added the tissue paper "tar paper" roof, the stove stack, the ladder,trim and some MacLeod Western On3 Russel trucks. The couplers took a little fiddling but worked out well. Not a perfect TV caboose but looks nice on the layout and I think I'll keep it!
