Michael, Keep in mind that the Freightliner COE is designed to be built either as a day-cab or sleeper-cab. As a result, there's a nasty seam up the sides and along the roof. The sanding required to blend the seam often results in the (out-of-scale) rivets being sanded down and having to be replaced. If you decide to build a cabover, you might want to select a different kit (Peterbilt 352, Kenworth K123, GMC Astro, etc...) Good luck with your first heavy truck! -Ken
