The cake is 2 loaf pans stacked and carved. The wheels are RKT covered in fondant. The truck is sitting on top of 2 RKT blocks behind the tires, not only does it hold the cake up, it also was used as support to hold the tires on using a dowel rod that went thru each tire and the RKT blocks. The cake is on a board with dowel going thru the cake,board,and RKT blocks. I hope this made sense...TFL!!
