A body for rover

We know that there is no cuboid body readymade we need to make it cuboid manually for rover so my suggestion is that if there are premade parts for rover such as a poly blend body , an antenna to communicate with rover, a drill to drill ore and finally in game side rover wheels with suspension so if we need to make a new rover we just need to assemble It. It will save lot of time and people will start making more rovers with enthusiasm
