Wow, excellent progress so far LemonJello.
I spent this past weekend and yesterday (almost 30 hours total) struggling with my Ural. As far as the frame and cab go, nothing fits well. I had to glue in all frame pieces, used a jig to alligh, and it still didn't line up properly. At least I managed to get all wheels to touch the ground evenly. I had to remove some frame cross-members, as I want the engine to fit, and if all pieces are included, it clearly does not. The cab mounting parts were sanded to fit, and the engine oil-pan had to be sanded down part-way to be able to sit squarely on the frame. I decided that I want it covered by canvas, so (not shown in pic) I cut some strips from styrene sheet and glued them onto the modified sides of the rear to be able to drill holes to accept canvas support beams. I also decided to build the BS-100 gun as a companion piece. THe gun is finished, but the pic only shows the barell in it's craddle. Sometime this week I'll be basecoating everything in Model Master Acryl dark green.
Here are the major subassemblies, minus wheels, doors, and few other parts, ready for paint:
