Vincent, the build is near perfect. Your detailing is pretty much spot-on. Two small gripes: your headlights are a bit too low, but that is nearly impossible to fix, and the M998 is a soft top-soft door cargo variant. Yours is an M1026/M1114/M1151. The hard top versions were built as hard tops, and had different designations. Those are just nit picking because the build is so perfect. Regards, Eric.
At 10 studs wide, I personally think it's a bit wide for minifig scale, but knowing you and how much research you put into your MOCs beforehand, I am probably totally wrong about this... Great work again Vince!
