the current roof is 30 years old and needs to be replaced. that’s why the appearance of the 5th wheel hitch ensures that the weight will be placed safely towards the center of the truck, making it remain stable all the times. you might notice not all the blocks are square! you can decorate them to fit any holiday or celebration simply by changing the colors of the tissue paper. i liked this book because i like to find the clues to solve the mystery of the missing present.
