It sounds like this truck has been updated with a v8 so you need to find out what rear end and transmission it has and what suspension changes have been made. If it has a newer passenger car rear end with high gear ratio for highway cruising and fuel economy it may not be the best choice for pulling a heavy load. If the suspension is modified it may not be able to carry the added wieght safely. you need to do your homework to see if it will fit your need. you can solve all issues by throwing money at it but you need to determine what is right for your budget and need.
