These kits are slightly more expensive than our normal kits due to the added challenges and printing to make them with the cab seperate. But i make sure i still stay well below the price of my competitors for the same quality. ..to my awesome customers  please understand that all items are printed to order as i am a small home based business with a large number of items and a full time job on top of it all.  sometimes i may u8p a few days to a week behind on shipping due to life being life.  that has especially been true as of late  i am always trying to the utmost of my ability to get your orders not only out on time but made correctly  this sometimes means reprints on your products to make them right and up to my enduring standards  I truly appreciate each and every one of you and will continue to strive to bring the best 3d printed models to the hobby sector.  thank you ChrisAll kits are shipped on supports to prevent damage in shipping
