Hi Roy, thank you for your review. We appreciate both your feedback points but we chose not to do either in order to keep consumer costs low. By not including roofing material, the product price can stay low and customers can chose what roofing they wish to buy, and if we switched to each vehicle having a forklift, our costs for drivers (with additional training) and more expensive to buy and maintain vehicles would mean our prices would need to increase. Instead we put our money in ensuring the best value for money products. We are glad you like the design and hope you enjoy your cabin!
