Here is a pair of hot asphalt trucks from Bryan Ross. The model on the right is a Boley GMC Topkick used for smaller jobs by his fictional construction company, LSC. The model was made from a spare milk tanker (shortened) and a scratchbuilt sprayer system. The model on the left is an International 7600 with a slightly modified tanker body and a scratch built sprayer system. The arms on it can be extended for heavy duty applications such as highways.
